Also stop fucking arresting people for living in unapproved locations or building structures that don't cost enough money, as long as they're not actually in the way of anyone.

Like, don't arrest people for sleeping under bridges unless they are sleeping in the middle of a footpath under a bridge. And don't go building footpaths under all the bridges to prevent them, either. Also tear down all the hostile architecture or at least don't arrest people for taking to it with angle grinders.

The free market is supposed to work by everyone solving all their own problems and then exchanging solutions with each other. If you claim to have a market but then arrest people for solving problems, no wonder you get a dysfunctional society.

Not saying that people living in tents on public land is a good long-term solution, but it's a step up from being completely shelterless, and since price changes happen at the margins, if it's even remotely viable, it may cause a market crash.
