Learn to shelter in place and stand your ground.
California and NY, not so much.
Sheltering in place is resigning oneself to being surrounded by decay and decline. And increasingly in danger. No thanks.
Moving can significantly improve the quality of life. Its not an easy decision, and certainly not without its challenges, but the long term rewards and peace of mind are potentially worth it IMO.
Except for states as you said, like CA, where it's you who are behind enemy lines...and you're enemy.
Think about your home's market value. Think if you're standing on ground or shifting sand.

An entirely different thing. Is any place worth it to you if you have to hunker down until danger passes, if it does pass at all?
Think, too, if you can rebuild and recoup after losing everything. Which sometimes takes only a matchstick.
TOTALLY DISAGREE IN STRONGEST TERMS.
