Except those chronic addicts, alcoholics, and seriously mentally ill -have- resources available, but often choose not to avail themselves of them for any number of reasons. And, due to the evolution of involuntary commitment laws since the 50s/60s, thanks in large part to the talk therapy crowd going out of their wheelhouse, and the ACLU and credulous people taking "One Flew Over the Cuckoo's Nest" and The Snake Pit as documentaries, and budgets being moved to useless but cheaper "Community Health Centers" instead of in-patient mental institutions, those unfortunates cannot be effectively confined for treatment nor for their own protection. Instead we humanely, and high-mindedly, and oh so "virtuously" leave them to die on the streets.
