What do you geniuses suggest? Should we undertake the construction of a gigantic sea wall along the Atlantic coast? Environmentalists might have a problem with that concept. How about suspending the Constitution for a while and force American property owners to abandon their coastal property? Which businesses should we authorize to operate on the coast? Just the gambling casinos?
So you have to go hyperbolic even on the simplist points.
A store of sandbags adjacent to the subway entrances would not be a really big deal. A tree trimming program along the overhead power lines that are most vulneble to being downed by high winds is not budget busting for a utility.
What you are going to get is a situation where the Federal and State governments state that if you build in a certain area, you will get no help beyond that required to save lives. And the insurance companies will not insure your home for any amount.
And what does this have to do with the Constitution? Nothing in the Constitution states that the Government or Insurance companies have to cover you if you are stupid enough to build in a known hazard area.
The people operating and owning property in the at risk areas on the coast are going to have to realize that the rest of us cannot bail them out for rebuilding in an area known to be repeatedly in harms way.
Nobody says that people have to abandon their property. Just that the rest of us will not continue to pay to have the buildings continually rebuilt and destroyed. You have the money to do that, go ahead and build. And when that is destroyed or damaged, if you can afford it, build again.
