In theory, sure. In reality the racket between insurers, government and banking will find strings to pull so that that never happens. They're in on every deal. They're gonna fight tooth and nail to prevent the precedent of getting cut out.

I don't think it's fundamentally uneconomical to live in these places. It's just uneconomical in the current "nobody has any responsibility for anything it's all just financialized away" status quo in which it's ok to have plastic siding over a plastic-wood structure and shrubbery all about status quo. People will have to return to the "old ways" of corrugated steel, clapboard (or masonry or cement board) and super short grass and dirt for large distances around structures.
