All rent is bad and all forms of landlords are evil. They are a separate class with legal mandate to steal the labor value of the working class. They serve no function whatsoever and it is entirely conceivable that an apartment building's occupants could pool money together for repairs when that is necessary.

Shelter is a human right. Housing is a human right. Landlords are not mechanics, they are not repair men, they are not construction workers, they are not laborers. Some Landlords may do some of those things, but it doesn't change the fact that by virtue of stealing from the working class they are still evil. If they want to do repair work, I should be able to simply pay them for the repair work they do. If they want to do property maintenance work, I should be able to simply pay them for the property maintenance. They have a legal document enabling them to steal half of my income every month for no reason. They do not live in my home, I live in my home. If I stopped living there it wouldn't be my home anymore.

There are 0 downsides to entirely rejecting the housing market. Housing is a human right, it should be fairly distributed to everyone. I couldn't give a fuck about real estate markets, they could all dissappear today and no one would ever profit off of housing again and not a single tear would be shed. I'd really like it if everyone could have a fucking home. All Landlords are evil. There are NO exceptions. If they collect rent for someone else's home, they are evil.
