I mean, I guess you'd have to read and know about the island and its surrounding geography to understand how this isn't really that feasible. For one, the island and the harbor is tiny. The dutch system is vast and includes stuff like sand dunes, jetties, dams, etc that simply would not fit in the space that the island occupies. The houses are worth millions of dollars precisely because of the access to pseudo-private beaches and boat moorings. Even if you could do it, I cannot fathom the cost of building something like a large levy system that would only crater the price of homes on the island. Additionally, it would render services that provide convenient access on/off the island untenable. I could go on for a while about this, but it really isn't practical or feasible for this particular case.
