Well then, sounds like a problem that can easily be solved with the meager expense of public facilities, trashcans, and open spaces that aren't sidewalks for the unhoused to hang out in.
They want to go wherever they want to, camp out wherever they want to, they want to collect whatever garbage they want to and they don’t want to clean up after themselves, they want to do as much drugs and alcohol abuse in public as they want to, they want to piss wherever they may happen to be at the moment because they don’t want to be burdened with the responsibility of thinking out their actions.
This doesn’t describe every one exactly but it generally describes most that fall into this category.
Ultimately these are people who refuse to play by the rules of society. No amount of public support is going to change them because they simply do not want to change. They are perfectly happy where they are right now, doing whatever it is they want to do. Nobody can solve their ‘problem’ because as far as they are concerned there is no problem.
So understanding that fact, society needs to decide just how much of that behavior it is willing to tolerate.
people who are not so extreme perhaps fall into the first category. I mean, I know people who live free because they want to. They don't cause any issues to the public around them except that they don't pay local taxes and are therefore a burden on the state in some minimal way (simplistically, they do use the roads and other services provided by the government). If housing were cheap enough they might take advantage of that.
(How do these people get into this state? Is this just a concentration phenomenon, where people who think that all move to the same place?)
Which is why it is so perplexing that Bay Area progressives strive so hard to protext libertarians.
Santa Monica had a bunch of public restrooms and you NEVER see poop on the street like on San Fran.
