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.
Maybe you don't understand property rights, especially as you seem to confused on the topic, but I guess it also depends on which country you live in. Many developed countries will have quite strong legal systems and independent judges who do not bend to changing government politicians. I'm not sure why you think bitcoin, which most people will generally store on a physical device, is any safer against government seizure. The fact that you say the soviet system the government assigned you housing, like it was some special gift that a citizen should be grateful for and could be ripped away at any moment, shows quite a brainwashed mindset. If you do not support the singular government, however broken and corrupt it was, your right to live in a house would cease to exist - that is completely different to a capitalist system where you'd have a fighting chance to keep your paid off home.
