This question is practically as old as time. Politicians have been trying to relocate labor and industry for centuries now. Ideas have been proposed and tried, and every place that has been successful has a hundred different competing explanations for why it was successful, and the same goes for the places that were unsuccessful. The matter is complex enough, and success rate low enough, to be able to confidently say we don't know really how to do it. It actually is easier to reform cities than it is to relocate everybody that is made worse off by their poor decisions. And since San Francisco's poor decisions are negatively affecting every city within a 100mi radius, it would make sense for the state intervention to be the tool that brings the change.
