Yes, those mental hospitals were terribly run. But we need to create a safe place for these people. We can't just give up because of mistakes made in the past.

many are drug addicted, they would have somewhere to go but they opted out of society (well, they aren't in the forest so not full opt-out)
but yes a combination of state run rehab / mental hospitals seems to be the only solution, but is it done by force?
if it's not forced you'll have a hell of a time getting people to go. if it is, you are now rounding up potentially unwilling people and shipping them to a facility.
Yes, of course. Do you really think most of these people even in the care of their own family would have complete agency over their lives? No, they'd be declared unfit and their Power of Attorney would be delegated to someone else.
Do you know that? In the US, I read (several years ago) that the top reason was losing your home to medical bills.
