If not for the social aspect of it I’d be on board also. I struggle to live that closely with others.

It’s the sort of thing I’d like to see done with existing abandoned malls, though. Might cost a bit to retrofit, but I think you could easily get away with shared facilities (bathrooms/kitchens) and separate living space, as long as it doesn’t cost a lot to live there. Make them communal living spaces that function as a whole indoor community.
