@georgetakei beachfront needs... well... beaches. You can’t just move the interstices off the sea and the land inward and expect sand to magically appear. If you’re really, really lucky, there may be a few spots ideally shaped and situated to let the ocean currents drop the sand they carry there, but they’ll be fairly rare. That whole “miles of golden sand” thing? That takes many thousands of years to really get its feet under it.
