> they cannot hold onto housing and they cause incredible damage in the cities where they congregate

You are right, on average they cannot maintain housing, which is why I said "subsidized" - which ensures they don't become homeless (aka publicly visible).

> We lack single unit subsidized housing in Portland

What that doesn't solve is the substance abuse, which is a mental health problem. If your intent is to solve both then you need to spend on mental healthcare and subsidized single unit housing. If you just want them off the street and concentrated to certain areas (eg: where I live in Portland) then you just need subsidized housing.

There is more to being able to maintain housing than paying rent. Are you also going to subsidize cleaning and maintenance staff to scrub and rebuild the apartment every time they deliberately destroy it? If you kick them out for smearing everything in feces or tearing all the copper out of the walls or stopping up all the drains and flooding the unit because the drugs made them think this was a good idea, then you haven't solved the homeless problem. You've just made another homeless shelter which they won't stay in because it has rules they won't or can't follow.

They need to be housed in something like a prison or a psychiatric hospital, after being convicted with due process.
