Note that he can only keep people out who want to cross his land to reach the beach. If they come in by boat, and stay between the ocean and the high tide mark, he's got nothing.
I wonder if one could make a profit with a shuttle boat service to bring people to and from the beach for a small fee?
Twice a day you'd need to move (and during any heavy waves); you have to stay below high-tide. Building structures in the water itself is itself a CC permit activity (as well as potentially involving the coast guard and army corps of engineers).
