You're absolutely right. This is a problem that requires some amount of direct government assistance. Beachfront housing is significantly more costly than people think it is and than it used to be, and it's only going to get worse. If you can't afford regular repairs after storms (or if a collectively relevant insurance pool can't), you can't afford to live there, and for people who are already there and can't afford to easily get out, some government assistance is more than warranted.
