What do they have to gain by restricting Bitcoin? A lot! Especially when the voting block that is demanding Bitcoin is not sufficiently strong over there.
What exactly could they gain?
Control? Surveillance? Continued deprivation of wealth for the majority of the population? Do you think that it is just a historical coincidence that we have extremely high taxes and high monetary inflation? The system is designed to prevent you from making big achievements, it is not designed to enable people to make huge jumps in wealth and status. This does not mean that it does not happen, but it is designed to keep the majority "in check". If anything, we are collecting way too much in taxes all around the world but most of it is being stolen and spent inefficiently. This includes the countries that rank the best in corruption indexes.
I have some insights into Europe as I know Germany quite well (having lived there several years). Yes, the Bitcoin adoption there is probably currently not strong enough for an important politician to take Bitcoiners into account and to block restrictive regulations. On the other hand, there is a strong appreciation for cash in Europe (except Scandinavia), and that will make it impossible for any "Orwellian surveillance" of payments to gain any popular support. If a politician in Germany for example promises to abolish cash and replace it by CBDC, he will lose his election without doubts.
(By the way, the European CBDC idea is more of a competitor to VISA/Mastercard and PayPal as European companies until now were unable to create a relevant payment system and so a lot of debit card and PayPal fees flow into the US every day. I honestly am more worried about surveillance in Europe when it comes to things like social media, where the EU with the pretext of combatting CSAM wanted to implement mandatory device scanning for media for WhatsApp and similar messaging apps. Fortunately for now they failed, but now they're going for "KYC" on social media exploiting fears about kids becoming addicted to TikTok ... , at least I read they plan this in France)</OT>
I don't agree with this analysis at all. I am quite pessimistic about these things, because we have to place them in the context in which they are happening. Of course there is an actual benefit here to be had by not having to rely on VISA/Mastercard and having lower fees, but this is not the reason why this is being done -- it is the reason through which the idea is being sold. There is a war on privacy and freedom going on in Europe, and because of this I can't assume that their intentions are honest or benevolent. Here is my forecast on what will happen with this infrastructure and the CBDC:
Step 1) Zero fee, sold as competitor or solution to some problems but keep alternatives available.
Step 2) The solution becomes widely used and the most popular one, slowly start attacking alternatives.
Step 3) (Optional) Introduce fees on both sides to start earning money.
Step 4) Make the solution mandatory.
Step 5) Introduce a social credit score based on the data generated by this system.
This might sound like a conspiracy theory to those that are afraid to face the truths of our reality, but this is exactly how I would do something like this. This is how they have always been implementing surveillance and extreme control measures, taking a small step at a time but never reverting anything. As you can see also with threats, once you introduce laws to battle some threats
there never comes a time where they abolish such laws.

Lastly, you have to understand that a government mandated solution can never be the same as one that is done by a 3rd party in the legal sense. In the case of a solution that is owned by the government, they have all the data on you right away. In the case of VISA/Mastercard, they need a court order to get it (even if it is a shady and corrupt one with basically auto-approval like FISA courts). There is a distinction regardless of who fails to see it.
Anyway my remarks were about a society where Bitcoin would have already advanced a bit more both as a means of payment as as a store of value (to save). The scenario I was discussing here is: a significant Bitcoin adoption which starts to have effects like a deflation (like more incentives to save) for their users and a growing merchant network, and beginning to affect the economy as a whole. We're talking thus at least about 20-30% adoption, more than in the US (~15%) today, and thus the effect on election dynamics would be even stronger than in the Trump/Harris election.
There is plenty of adoption to go before we have a chance to see how that would play out. The US is probably leading with adoption in the developed world, so there is even more to go with other countries..
I get your point, but I would say that this is slightly still too optimistic for me. Do you really believe that we have already completely gotten away from the bullshit and lies from Keynesian economics? Was it not Keynes that argued that even spending for war efforts was great for the economy, as in any spending is good?
You can easily debunk that with a very simple thought experiment: What if instead of spending for costs of war you provide goods for the same value to every citizen?
You tell those that have the power and those that teach the future generations in dogmatic universities that it is easily debunked, not me.

For example, I had seen a Putin fanboi here in the forum argue that "Putin's war is good for Russia, because the Russian companies will then rebuild the destroyed homes and roads in Ukraine and make a lot of profit!". But what if they simply built the same homes and roads without any war? You'd solve the housing crisis and improve transportation a lot

IQ measures are averages after all, we are generally clueless just how dumb a person with IQ of 80 or even 90 is.

Imagine some very grim scenario. Let's say that the US does not care about human rights at all or any war laws. They obliterate Venezuela and its people on a massive scale, something similar to what Israel is doing but just on a larger scale. They capture oil worth $10 - $20 trillion, among other resources. Can you be really sure that this scenario would not be economically profitable?
That would tank the oil price 
So no, while I won't analyze that in detail here, its still unlikely to be profitable, taking into account all costs. And if the US get too cruel, then they risk even getting sanctioned or boycotted (rare earths!). China doesn't really need the US market anymore.
Nice one.

Please do entertain my scenarios though without trying to find some details by which to dismiss it on -- I am trying to give ideas on some possibilities and outcomes where this may be true, without investing time to figure out a completely realistic scenario that is based on data (e.g., starting with the actual value of the resources that could be seized and making a warfare cost analysis which would be too much work and out of scope here). In my view,
there are definitely situations in which a war is going to be profitable. That does not mean that it won't come with a lot of chaos and problems, but even if the end result is +1$ it is profitable. Venezuela has a lot of people, but Greenland is a simpler example. It can realistically be taken over by the US in
single day of war. Sure it is technically owned by Denmark, but who cares? What are they going to do about it? The US stands to lose a lot from such a venture, but the EU will lose even more. Who are they going to partner with if the lose the US?

I wonder what is the value of all the resources that can be gained from a Greenland annexation. Furthermore, there is a lot of value in geopolitical positioning but that is much harder to quantify. I am sure that some analysts are actively running scenarios of profitability of warfare for the government. I would be really surprised if there weren't.
Think also about some other alternative world scenarios here. Things may happen for which the alliance between the US and EU weakens or completely collapses first. In that case, even less would be stopping the US from simply taking Greenland. It is a lot of area but the population is low and defenses are practically non existent. The world is complex, many combinations of events and unforeseen circumstances are possible.
Furthermore, I would like to highlight the current situation between the EU and Russia. The sanctions have objectively probably hurt the EU much more than they have Russia. Thing could only be properly evaluated were the same sanctions in place and were Russia not fighting an actual war. If we to subtract war expenditures and wealth destruction (and probably also we have to subtract the effects of sanctions of other countries to be able to compare what happens to each side respectively when 1 sanctions the other), everything that I see points out that the EU hurt itself more with this. The economic situation in the EU is terrible, with many industries suffering across many countries. Just don't try to get this data from the main news sites, practically all of them in the EU are corrupt (ironically they accuse the media over there, wherever over there is, of being a propaganda machine). Look at industry output, real wage development figures over decades and more. The same could be true in many future conflicts. While globalization tends to make losses interconnected, that does not mean that one side won't hurt itself much more by sanctioning the other. Therefore,
there is both an incentive to not wage war but also not to impose sanctions if there is war!
That said, we've good a long way to go with education, awareness and the money printer. As long as there is a money printer, and as long as it is not those that wage that suffer the consequences directly nothing is certain.
I doubt we need the money printer for that. Alternatively we can discuss deflationary scenarios, like here

IMO the main problem for the deflationary scenario with a deflationary currency (like Bitcoin) competing with fiat is the conflict of forces:
- on one hand, Gresham's law: the deflationary currency has a lower circulation rate, so companies exclusively taking Bitcoin will have less sales,
- but on the other hand, and this is specific to Bitcoin, the merchant advantage to not depend on any electronic payment system with fees, and later (in a Bitcoin lower-volatility scenario) to be able to use the funds directly for treasury and be able to benefit from long term growth, without having to invest it into risky assets like stocks.
- and in addition, also only if Bitcoin lowers its volatility, the advantage for "common people" to count with a currency they can use both for payments and for saving, they could get discounts at merchants, and even become conscient about the possible advantages if they restrict consumerism a bit.
As the first force only applies to companies exclusively taking Bitcoin, this will be a very rare case, so the most likely case is that they will take both fiat and Bitcoin. And this could evolve into the "ideal" configuration for merchants, and later also for customers if they get discounts. So I think there's a good chance that the pro-Bitcoin and thus the pro-deflationary forces are stronger.
Gresham's law: I do agree that a deflationary currency would have a lower circulation rate and also that exclusive Bitcoin acceptance would reduce short-term and even medium-term sales. Is that so bad though or is it merely a reflection of just how valuable Bitcoin is compared to an inflationary currency? Right now we only have some cases where we can draw from real world data from but they are not going to be that accurate for what we have here -- places where 2 fiat currencies co-exist or co-existed, and where one was preferred over the other for some reasons. However, both were inflationary by design. I don't think we have any case where there was a inflationary currency competing with a deflationary one? It is possible that we would see similar behavior, but nevertheless it should be pointed out that the chance exists that things would play out somewhat differently.
Merchant advantage: Yes, but I would say that the really beneficial advantages only really matter to a subset of merchants. Sure, lower fees are always good but stuff like censorship resistance is not what most people need or value. We value it, and it should be valued but we are speaking about the practical situation of the average merchant. Not that many have issues where they really do need that feature, and therefore not many would derive real benefit from it. I think that growth benefits and treasury would be more important for the average business but after volatility drops as you have indicated.
Overall, a lot of scenarios depend on reduced volatility, widespread adoption and maturity. Only once all of these are checked can we actually evaluate what is going on and how much benefit is being derived. Until then we are more in the theoretical area, or in terms of practice in the risky area. I mean, I would advise business owners to invest a bit of their profits in Bitcoin already. The risk is higher, but what about it? A small allocation can, at worst, do minimal harm.
The most obvious example is the increase in fuel prices some time ago and any increase or adjustment in fuel prices will definitely have a direct impact on public protests,
political pressure and some defensive response from the government because the impact will be felt directly by the public even though they theoretically do not understand what is behind the policy.
Fuel price driven protests are indeed an excellent example that unpopular government decisions can put their power in danger. And yes, as you write, that can also be the case if Bitcoin is restricted.
What have these protests actually accomplished? Can you give me
recent examples where they led to really lasting changes rather than a simple shift in the leading political party? I am doubtful of the current capabilities of the average human to protest anything that is worth defending, but I'm happy to be proven wrong on this. When I talk about "worth defending" I am referring to freedoms and rights which when taken away do not necessarily have instantaneous tangible negative effects, such as would be the case if food was taken away from people. To be honest, in the current world that we live in
I believe more people would riot if you took away McDonald's or Instagram than if you took away some of their important freedoms or human rights (Bitcoin included).
