In the practical sense, you're almost certainly right. In fact, no one probably ought to be living on the beach in south Florida. Certainly not in trailor homes: it's too damned dangerous.
At least those who have to lose their homes against their wishes will get some money out of it. Could be worse.
Ironically, it may be more of a loss for Florida as a whole than for the residents of Briny Breezes -- or whatever the silly name is -- themselves. If I understand it rightly, that part of Florida is getting even more over-developed than the beaches in Hawaii are. High rise hotels and condos cheek by jowl for as far as the eye can see.
