I think the issue is the term “mental treatment”. Do you want social workers to come by once in a while? Of course: Have a talk, ask whether everything about the apartment is in order – not an inspection, more the “if the drain doesn’t work and you don’t know what to do call us” kind of thing. But that’s not therapy, it’s at most psycho-sociological counselling. Therapy in most cases won’t even work because there’s the bulk of people’s core issues is shitty life syndrome and there’s no pill against capitalism.
