All the facts you state about the environment are true. But it makes zero sense IMO to make this an individual decision governed by the whims of the market and replicated anew across every single person. That is a purely reactive stance and, being humans, we can do better than that.
We are smart enough to be proactive about these sorts of things, and considering we already have such an apparatus called "the state" to use to our benefit, we can provide assistance to people to reinforce their homes or move when necessary (in a rote economic sense, to keep them net-positive productive, in the utilitarian sense; in a humanistically compassionate sense, to keep them dignified) instead of trying to guide systemic patterns of behavior by punishing individuals for making impossibly complex choices regarding where they chose to and already do live.
