If these people want to pay for their own sea walls to protect their homes, fine; but taxpayers shouldn’t be subsidizing the ultra rich to protect their properties. Buying ocean front property in this day and age is a big risk.
I see, there are different ways to do them. In some ways, the public will need to fund some seawall construction to protect roads and reduce erosion overall. Highway 1 in CA is a good example. But, there are also plenty of examples of people who built homes dangerously close to the ocean and when a big storm rolls in, they get wrecked.
