Again, I see someone lumping "the homeless" into the same human pot - "NONE of them want to abide by any rules."
That is simply not true. Plenty of homeless Seniors, for example, have no issue with rules.
Then you have homeless addicts who yes, may have an issue with "no drug use" in the home. Ironically, any wealthily person can rent out any AirBNB in the Hollywood Hills, procure $100,000 in illegal drugs easily on the streets of L.A. or via the Dark Web, and they and their buddies can break all the laws of society they want in their party rental home.
Society says to the poor man addict: "We're subsidizing your rent, so no drug use for you!" But society says to the AirBNB party house renter, "Go ahead and feed the drug trade. It's OK. We like you because we're not paying part of your rent."
But the wealthy partier is still causing harm to society. He might be exposing someone to drugs for the first time at his party. Might have called over a few prositutues also (another crime). Might have plenty of underage people there drinking. He might have bought a bad batch of drugs and a few people OD. And he might be disturbing the peace.
But society does NOTHING to him, usually, because he's a good capitalist!
Addicts need treatment and housing. But your first requirement is rules. Not rules for the RICH MAN who rents his AirBNB party house. Just rules for the poor schmuck who dares to ask society for help.
No one is above the law/rules BUT the rich. Everyone knows that's how the system really works - for housing, college, legal cases, etc., etc.
