Blame the system that makes it arbitrarily difficult to transition between houses, which is in part exacerbated due to the fact homes are being used by parasites as vehicles for profit generation through rent seeking models artificially increasing the floor price of homes.

What you're mad at is the private property system inherent to capitalism restricting what you're able to do because of arbitrary bullshit. Why do you need to purchase a house in the first place? It is empty and not being used, so why does the previous owner still retain control over it and be allowed to arbitrarily prevent others from using it unless we can satisfy their greed? Why do we support a system that arbitrarily restricts our access to basic necessities in such a way and just glazes over such blatant exploitation?

Instead of trying to justify exploitation under the current system, how about we think about changing this system to one based on the needs of people instead of one based on imaginary, monetary interests and the whims of greedy fucks who retain illegitimate control over what should rightfully belong to the community?

In a system of community property, any vacant homes would be readily available and the ownership of units transferred from communal to personal property based on usufruct where, so long as you live in the home, it belongs to you but, when you vacate to a new home, the ownership is transferred back to the community.
