I'm against clearing homeless out of parks given we live in a world where standards of living in between "homeless" and "a properly zoned/fully inspected building" are illegal.
Like, someone could buy a plot of land, build a bunch of tent-sized pods and rent these to live in for a tiny fraction of the price of normal housing. But despite this being an upgrade from homelessness, ppl would see it and go "wow that's inhumane, we can't allow this"
"What if we could profit off of charging rent to homeless people" is... not your greatest idea yet. Landlords exploiting tenets is common enough without removing all regulations and pulling extra vulnerable people into the mix.
Also it doesn't really sound profitable because in most big cities where a lot of homeless people live it's the land itself (not in infra) that's expensive.
sure, while you're working on that i'd be ok just removing prohibitions against homeless people slightly improving their situation. And then we can try to get them up into a house. But this either-or approach is just keeping them on the street.
