I'm from eastern Europe. In the soviet era noone could own private property, everything was belonging to the state. Then, the state rationed food to you, allowed you to use one of their homes in exchange for labour, allowed selling produce on government-controlled prices, and buying in predetermined quantities.
So let me ask a question. When you buy a home with all your life savings, does it become yours? What makes it differ from the soviets? I mean, obviously they recorded your rights to the building on paper, and now they record it in digital databases. But is it REALLY that different? You don't truly own either. It's all the government's promise to let you access it and keep away whomever should not access it, until they don't.
The only thing you truly own is bitcoin. The rest are promises.
This is a very interesting topic but I think differently about this subject. I really think that it's not much different from communism what we have in our world because as you say, you couldn't afford private property in communism and today you simply can't buy it, so? What's the difference? If I can't buy/get an apartment, it doesn't matter for me whether it's a communism or capitalism if the outcome is the same for me.
The fact is, in reality, communism is bad but capitalism is worse over time. Capitalism is only good in the beginning but it always ends up badly. Rich people do not love giving money away, they tend to love collecting more as their income growths.
