I see this take a lot but it's a very static take on homelessness.
Yes, homeless people are often in a mental state where they are difficult to take care of. However, that doesn't mean they're homeless because they're mentally unstable. Often, the reason they are unstable is because they are homeless.
Being on the street heavily exacerbates drug and mental health issues. Plenty of homeless people start out normal and then fall into this state. So if you want to reduce the number of crazy people on the street, then people need stability and homes to cut off the pipeline.
