I'm not trying to be disagreeable tonight but I differ. This is like saying no homes near a fault line, rivers, tornado alleys, blizzard areas etc. People should live where they want but build for protection.
New Orleans is obviously not in a good spot, like on the side of an active volcano. Take a look sometime. It is as exposed as Galveston was in 1900. I am reminded of Venice, which is, sadly, sinking into the sea.
