Is it time to start moving our coastal cities inland?

19. There is no such thing as a city

There are reasons people live within a certain area and they have everything to do with geography--even though we often think otherwise. Throw out any dozen alternate histories of the US and you'll always end up with a major urban hub in New York, one in the Gulf where the Miss. River terminates, another where the Miss. starts, San Francisco is on a fault line, but it will always be a major city.

If things change, the city will "relocate" itself, but usually in pieces and relatively slowly. You don't move NY, but if it isn't feasible for the financial businesses to continue on Manhattan, they'll move their headquarters--maybe to Chicago, LA, Boston...where ever they can operate efficiently. When/if they move, there is less reason for other businesses to be there and they close/move their business. In a few years, NY is no longer the center.
