What we need is a mandated and enforced vacancy tax nationwide. Make it high enough to fix the housing crisis.
*Edited to add: according to the Wikipedia article I linked, Canada and the USA have cities that have implemented vacancy taxes. We need to do like France and Ireland and make it nationwide.
I know what you're getting at, but saying "there is no rule of law anymore" is a bit hyperbolic. The cops, at least in my city, are still arresting people. You make it seem like we can just do whatever we want now. This isn't The Purge.
