Do you really think that raising (e.g.) gas prices by a large margin will somehow redirect resources to getting more gas into those areas?

* The gas stations without electricity aren't to get electricity any fast because the price of gas is higher.

* Gasoline shipments aren't going to come any faster.

* New gas stations aren't going to pop up as entrepreneurs move into the area to capitalize on increased demand for gas.

A disaster isn't necessarily a 'market force.' No one is going to get supplies into a disaster zone faster because they are trying to turn a quick buck. Especially since it isn't like they can setup shop and expect the increased prices to persist.
