The utter lack of it? There's an entire industrial complex around homeless "support" to do magic tricks on money.

Portland's county allocates $9m annually. LA's county allocates $4b annually. Should it be 2x that? 20x? 200x before any positive change occurs?

"Mental health" is a non-answer designed to shift accountability and agency from individuals into everyone else vis a vis whatever system is expected to provide this vague "support", despite the failed track record of these systems to improve anything but their employees' and contractors' pockets.
