Why at the state level? Why should people in other areas of California be burdened with poor decisions by a particular city? San Francisco has created conditions that encourage vagrants to flock to the city by simultaneously not enforcing the law and “supporting” the homeless with vast funds paid out to many inefficient non-profits. Add to this a lax policy toward camps and it is no wonder there are huge problems there. I don’t blame the vagrants for going there. Cities try to encourage growth in cities by making it attractive to employers. Why not discourage growth of vagrants by making it unattractive to break the law and camp out on sidewalks?
