It sounds like we're quibbling over the definition of "destroyed"... if a home is rendered uninhabitable for days/weeks/months, I'd consider that "destroyed" even if the framing is in fact salvageable.

And certainly as it relates to insurance, the trend sure seems to be well on it's way towards "coastal Florida is insurable" (either the price goes up beyond the means of the residents, or the insurers leave the market). Something like 5% of the state is covered by Citizen's Property (the government insurer of last-resort). Some coastal areas are ~10%. I have to imagine it won't be long before it's cheaper to pay people to move elsewhere than rebuild where they are.
