Why would TFG think that rising sea levels would equate to "more oceanfront property"?
The amount of coastline you have depends on a lot of factors, including the shape and indentation of the coast, but all other things being equal, the higher the sea level, the less shoreline you have–and eventually you have none at all. That's basic geometry.

More NEW oceanfront, that you can buy now for cheap!
@DavidSalo
Those are just man-made reefs, another plus for the new property owners ;^)
