capitalism competely collapses without the housing market being one of the many debt carrots converting perceived labour into cash.

I'm not forcing anyone to do anything. But if leech landlords (as described in the meme) are on the chopping block (regulation) I'd happily drop the cleaver/vote in favor.

I dunno about this one. Maintaining residential areas does take some work. Bills and all that do have organizational skills. Is it a 40 hour a week job? Depends on how big it is and how many residents there are.

Landlords existing isn't a boring dystopia. Pick a different community for the meme.

Problem with banning them outright, is where are all the people who can't afford to buy a house going to Live?

Sure, house prices might drop and some people might be able to buy. What about the rest?

Make them homeless?
