Before all these price gouging laws, in natural disasters there used to be marginal producers (people with a pickup truck etc.) who would load up on some supplies like ice etc. and bring them to the area that was hit to make a quick profit.

Rooftop solar is far more expensive than solar put on land. The cost of rooftop solar (particularly homeowner solar) is usually hidden by implementing a big subsidy to wealthy consumers that is paid for by less wealthy consumers - sort of
