I agree with you. I think property is theft; in an ideal world everyone would have the right to shelter and no one would own land privately. And I also think fear of housing insecurity - including the fear of a landlord extorting or evicting you - is the biggest reason America is obsessed with home ownership and I can’t criticize anybody for pursuing it. The only way to have secure housing in the US today is to own your home, and everyone has a right to secure housing.
Same as when one of the big name hosting companies takes a site down. You hope it’s archived, and if it was important enough to you, hopefully you saved it to your personal server.
What you’re describing is a major benefit of federation. Any site can be taken down. But when a federated server goes down it’s because the site owner exercised their control over their own data. If Google or Amazon takes a site down, you lose your data, but they keep copies to use however they want.
