Sounds like a great money making opportunity.
Surprised entrepreneurs aren’t bringing in pickup trucks full of 5 gal cans and selling for 10 bucks a gallon.
The only way to make it work is to bring an entire tanker truck filled with gasoline to a place where people need it for generators rather than for their cars. As time goes on and more and more people (and gas stations) get their power restored, your ability to get a huge premium on your fuel diminishes.
