Human Water Use Accounts For 42% of Recent Sea Level Rise

re. Outer Banks: I don't think you'd lose their buffer characteristics overnight; you'd have to wait until they were under something like 30' of ocean. They're still there and able to temper/stop any storm surge from hurricanes.

re. aquifers: why would you want to pump it anywhere? You fill the aquifer with the water that is still uphill by damming it up while it's up there - it's less energy-intensive that way. Problem is (if Oregon is any indication), building a dam is politically impossible these days.

re: ground water: A big problem is that some aquifers (e.g. the Ogallala) span multiple states. Who gets to pay for, manage, and regulate that?

One more bit: In most of the Western US, water is a very touchy subject. Water rights and ownership is separate from property and mineral rights (e.g. you can often own the dirt, but not the water to be found in, under, or on it). Except for parts of Oregon and Washington, you will find water rights, ownership, and laws to be a byzantine and brain-hurting mess to sort through. That it works at all without physical violence breaking out is a miracle.
