Other people are doing a good job pointing out the theoretical and moral objections to this, but let me also add a tactical one. Libertarians, if you want to swing more people around to your way of thinking, let this issue go. Price gouging during emergencies is not the hill you want to die on: it pisses people off at deep, fundamental level, and validates the worst stereotypes of libertarians as people eager to sacrifice (other people's) lives on the altar of the free market. Pick your battles and don't push on this one.
