Those aren’t the ones who housing-first advocates are building units for. The theory is the crazy people on the street will suddenly be not-crazy when they get an apartment
The vast majority of homeless people are homeless for economic reasons, like the loss of a job or household income, and the largest growing population of unhoused people are entire families.
The ones built in my town were for the “chronically homeless” these are people who are likely addicted, mentally ill, or very antisocial. They have burned every bridge they may have had and even their family has written them off. You can’t give someone like that an apartment and expect they will take care of it without extremely close supervision.
The lack of the ability to sleep securely and the lack of a place to store your possessions are enough to drive someone crazy. Sure, some people might be homeless because they're incurably insane, but plenty of people are insane because of homelessness.
> Drug-addicted and mentally ill people do not know how to keep even a moderately organized living space.
Which is nonsense and a damaging stereotype. Drug addicts and mentally ill people exist in all areas of life and many are successful - more so than you or I.
Secondly, I'm challenging you on:
> The theory is the crazy people on the street will suddenly be not-crazy when they get an apartment
Because in fact there is now a great body of evidence that shows that housing-first, that is providing housing with no pre-conditions, is in fact extremely effectively at treating both uncontrolled addiction and untreated mental illness.
Proposed housing units are literally for them.
