I deeply understand the points you are trying to make, the world today is more like a rented place even from our birth you can see that you are not assured of living but very much guaranteed of your death and the mere fact that you will temporarily here, furthermore; government or individuals that we elected to represent us in the day to day running of our countries now force everyone leave their properties in their hands to share amount us, it’s really bad that we can’t own lands for really, it’s all rented, we pay taxes for everything which also a subscription for living in our fathers land… infact in general the live we live are rented, when they decide to take it away from us they can. What a terrible life.
You're right but you're also letting it beat you and that's just what they want. Yes we're born into a system we didn't choose. Yes the land is rented. Yes taxes are subscription fees for already. Yes they can take it all away whenever they choose to. All of that is true. But we can see the cage quite well. We have language for it. We have the tools to create alternatives. Our great-grandfathers didn't have encrypted communication or decentralized networks or the ability to transfer value across borders without having to ask for permission. We do. So yeah life is rented. Death is guaranteed. The government will take what it wants. But sitting in that despair is just another way of paying rent.
In my country, we have schemes of "Rent to Own" for Condominiums, which is essentially renting until you fail that 1 month of payment and it's all gone. It's masquerading the OG way of handling debt because of saturated real estate markets and over development of cities. Inflation is on the high and the dreams of owning a piece of land is a distant dream, Buying it would tie you to your jobs at the expense of your dreams and family's aspiration. Rent is not bad, atleast not as bad as owning a property with less than 1% rental yield.
That rent to own business is nuts. A single late pay and decades of equity simply disappear. It is made to appear as a road to ownership yet it is in fact a method of taking the most rent. Worse than direct renting since at least with direct renting you know what to expect.
...Nothing is certain again because there are laws that have taken away your power to own anything. Job security is gradually becoming a mirage because they have been able to subdue labour laws through middlemen and temporary employment.
Small and medium-scale businesses would have to close down or become middlemen for large enterprises owned by politically connected businessmen. Since they cannot compete, the only option is to become enslaved...
It's not even about the middle man taking a cut (though obviously they do). The whole structure is now restructured in such a way that to survive, being a middleman is like the only option left. Like you can't just make something and sell it anymore. There's always a platform though, always a processor, always someone who "facilitates" and takes their piece. And we're supposed to be grateful for an opportunity to be efficiently exploited?
Maybe that's why decentralized stuff is important. Not because it'll make anyone rich (it probably won't) but because it's something that you can actually own.
What do you mean by
decentralized stuff? Bitcoin? Then I'm going to disappoint you.

You (no one) can own a
decentralized stuff like bitcoin, because, in fact, even during transactions, no bitcoin is sent to the recipient's address - only information about "ownership" is transmitted. You retain this "right" as long as you have access to your wallet (ownership of access keys - seed phrase). It's also worth noting that bitcoin simply doesn't exist in the physical world.

These are the "harsh" times when we don't actually own anything.
When we take such an argument to its logical conclusion then what would even counts as ownership anymore? Everything is information today. Ownership is the just whoever controls the database right? By that standard nothing's real. Then, who has the keys becomes the answer. With bitcoin its you (assuming you don't lose the seed phrase which yeah is a whole other problem). With literally everything else it's someone that can override you whenever.
You're right that we do not own anything in the old sense anymore. But there's a difference between "I don't own this because it's abstract" and "I don't own this because someone else can take it". I'd rather own information I control rather than stuff that someone else has a right to confiscate. At least I know where I stand.
