I love a beach as much as anybody, and have spent a lot of my life living within an hour or so - often within minutes - from a beach. But I don't think it's reasonable to keep putting perpetually at-risk places back together in much the same way they were. First, front and second-row beach dwellers should bear a larger proportion of the cost of living there than others in the community. F'rinstance, power lines to beachfront and nearby should be buried - and if there's an increase in cost to do that, the homeowners should pay it. Building style and materials should be built specifically to be storm-resistant. And eventually, it may be necessary to consider the area, in car-wreck terms, as a "total loss" and not try to rebuild.
Louisiana people are used to storms/hurricanes, and have had a bit of a blase attitude. But that's because it used to be that the bijous swamps, and boggy land between the ocean and the mainland protected against the worst. By the time a storm hit New Orleans or New Iberia it had been tamed down a bit. But somebody had the bright idea to "drain the swamp," and much of that protection is gone. Times and conditions change. You can't always go back to what was.
