If you prefer to blame homelessness on mental illness, you need some kind of explanation for why homelessness has tripled in ten years, and why it's highly correlated with rents and anticorrelated with vacancy rates.

From what you linked: "A qualitative study highlighted the basic human needs that often take priority over seeking psychiatric care. Access to adequate nutrition, water, shelter, and protection from the elements are the reality homeless individuals encounter daily, and these issues take priority over psychiatric needs, which are often not addressed until a crisis occurs."

Forcing the homeless into psychiatric care without their consent is skirting around why psychiatric care is currently inaccessible. People die rationing insulin, something tells me Uncle Sam isn't going to provide bipolar people on the street with free lithium. Plus people have good reason to distrust their doctor, a non-zero portion of homeless people ended up there after being prescribed Oxy and getting addicted to opiates. Substance abuse is driving most of the disparate health outcomes, and is a mental health issue but more importantly a public health one. The US as evidenced by the lack of a pandemic response does not care much about the public health.

I have good insurance. And supportive parents. I found navigating my diagnosis and care difficult, and I don't live on the street. I feel as though some of the commentators here have never experienced poverty nor can they empathize at a basic level with the struggle. It just seems as though psychiatric wards are meant to disappear these people since we can't disappear the underlying problem: commodification of shelter, water, food, knowledge.
