Would you feel safe in an ocean front house up on stilts?

Another tv question. People are buying 800 sq ft frame homes built on tall stilts right on an ocean for under 200K. The idea is if the ocean waves increase to 15 feet high you’re just fine up on your stilts. I think it’s a con and I’d be scared to death. Would you feel safe? I think the sand would get saturated and the stilts would fall down. I’m a land lubber.
