Hate to break it to you, but most "De-Fi" protocols aren't as decentralized as they claim to be. Developers are just using the term "decentralization" as some sort of buzzword to help attract people into their projects. This is why it's so easy to enforce regulations on so-called "DEXs" (decentralized exchanges) and/or "De-Fi" protocols.
Nicely said, but imho a bit incomplete.
I expect EU politicians don't understand fully all the perks and they also expect the average Joe doesn't understand them.
And if they get some of the platforms "regulated" (i.e. paying tax) they are happy. Where they can they may block some IPs like they do for some of the gambling sites.
VPN and Tor will still work and they can't do anything about that, so the users just a tad more technical will be just fine.
The EU has usually been in favor of "anti-crypto" policies. After all, it don't want the Euro to lose traction. Christine Lagarde (current President of the European Central Bank) is one of the most notable crypto haters. So, we should expect the worse from the bloc in the long run.
On the long run Christine Lagarde will get retired from ECB. Actually in 2027 already. Sadly the main candidates to take her place are not significantly better.
On the long run POTUS will also change and I am truly curious what will be USA stance on crypto afterwards.
And then we will also see EU's move on crypto, if any. I don't expect really worse, but also not better, sadly.
