I believe NJ and NY are similar to TX in many ways. Especially in NJ beach reconstruction is an ongoing activity for a number of reasons and the primary one has little to do with rich people's homes---it has to do with the fact that the beaches are profit centers, both directly and indirectly. Directly through "beach tags" sold by municipalities and indirectly by all the businesses that are dependent on beach goers for their livelihoods.
Almost all beach towns are "part time". Go down in January and you could roll a bowling ball down the main street and never hit a thing. Their entire economy hinges on the summer beach crowd.
Another secondary "need" is that much of NJ and Long Island are protected by barrier islands. If those beaches are not restored they endanger not only the islands but the mainland they protect. Sandy cut Fire Island (a barrier island) in three pieces. That has not been restored and I am not sure of the future plans.
Few things are all good or all bad and maintaining public beaches are one of those things.
