Houses.

Houses.
You see, the answer is simple but there is just no will to do it because people do not care about the mentally ill. We scare people for no reason but their own ignorance. I would say 90% of the mentally ill would have a great remission of their symptoms if they had stable housing.
I am homeless, all I need is a simple fcking studio but even making a lot of money from disability I cannot afford one anymore and I get shut down by people who do not want to rent to me because I am on diability.
Poor people who are not mentally ill often do exactly that. Even some drug addicts can sometimes get together to rent a place to crash. But we're talking about the severely mentally ill here. They are unable to band together. I imagine that this is sort of by definition... those who's mental illness illness is mild enough that they can help themselves by working together... just do it. The remaining are on the streets.
Can we agree that different people have different urgent needs? I agree with you that you need a house. A mentally unstable person who can’t take care of themselves needs mental help. A person with hard drug addiction destroying them needs physical and mental help. Not all problems can be solved with free housing, just like not all problems can be solved with involuntary hospitalization.
That is unfair, as it implying that throwing houses at the problem will magically fix it. Houses would help, for some (many) cases, but it's a lot more complicated than that. Nor is it simple to supply those houses, and lack of doing so isn't just "not caring". It's hard. It's really hard.
