Do you think there are any real world examples where you would need to "float them in the air?"
Yes, in cities. We were talking about downtown areas. Not anywhere that has land available. So any housing project will be more complicated than "build houses".
You obviously think you are more moral than everyone else, but you've provided no interesting solutions. so there's no use talking to you.
This is not "house then where they are". This is the sane argument of put housing and move the people, not "There's no housing so I cast SOciALisM!" And poof it's solved.
Editing to be less rude because I think there's actually a real misunderstanding here.
Build houses in places (cities, not literal square meters) where unhoused people need to be housed. They, like anyone else that lives in a city, can use their feet and bikes and public transit to go from where their house is to another place in that city where maybe they shop and work like any other citizen. The suggestion is simply to give them houses.
I also disagree with suburban sprawl and NIMBYism, hence my comments about densification
We are on the same page. Where I see homelessness there is not space for housing, but there are places that could accommodate without a cross-country trek.
