I can't speak for the above commenter, but in a way street people in SF really are more free than employed people. If I were to break into a car and steal stuff I'd get jailed and released a couple days later, or even the same day. But I'd probably get fired. Whereas someone with no job would get jaled and released with no real consequences. Because the city refuses to enforce many crimes (basically, anything short of significant violence) beyond catching and releasing, the only thing keeping people in line are their employers and peers. And if someone doesn't have a job and their peers don't care about committing crimes, then a whole bunch of stuff becomes de-facto legal.

From myself. I mentioned it once before in this HN post (if that's what you're referring to)

Criminals can drive, vote, sell their labor, enter contracts, and are free to travel without legal emancipation.
