Most people who are arguing that being a landlord (as a class) are arguing that using property (ownership) as an investment (extracting value) is evil by it’s nature. By owning the home and living there, there is already a categorical difference. Most (although not all) people arguing against rentier behavior have no issues with a person owning personal property.
I do see your what you are trying to say, it’s akin to “slippery slope” falacy https://en.wikipedia.org/wiki/Slippery_slope
If landlords are wrong, then logically wouldn’t this other more reasonable and less exploitative thing be wrong too? (renting a room in a house you own and are living in) and no, not necessarily. Because it isn’t the same thing.
Or maybe not. Maybe renting out a room in a house you live in is wrong too. Frankly, it would be simpler to do away with all private property rights, and live in a star trek style egalitarian utopia. I would vote for that.
As long as I get to smuggle in some Romulan Ale.
I mean, people pretty regularly organize enough to build a state. It’s actually really hard to stop people from building a state.
Hell, literal cavemen built the first state.
Your initial question is how to build a co-op in a hypercapitalist hellscape. And it turns out, it is kinda hard.
