Would you mind elaborating on what you are afraid of happening, and what you think the cause is?
The problem is a learned helplessness of the electorate combined with reasonable voters leaving, resulting in people who want to double down on the status quo replacing them.
There is zero political will to enforce vagrancy, open air drug use, and private property law if someone is living in a tent. No standards == these people feel empowered to do whatever they want, while contributors to the tax base are treated poorly. I still get a ticket 30 mins after parking too far from the curb, and the city council does not like that I make a good income and own a single family home.
What I had in mind is that we need to solve those accompanying problems in order to make living in tents socially acceptable.
Tents show up on public areas and sidewalks because there are no better established places for them.
Trash accumulates around tents because there is no established garbage collection procedure like there is for buildings.
Maybe the solution is some kind of campground with a low fee.
Mainly though, this is a strawman. Tents themselves are not the biggest problem when they don't e.g. block a sidewalk, piece of public infrastructure, or a road. The problem is piles of garbage, needles, dumping sewage into lakes and streams, increase in crime, not-yet-criminal or never-prosecuted safety concerns (e.g. someone I know can no longer take an obvious bike trail to where they're going because of some close calls with aggressive barely human campers).
