Maybe those states could set aside a portion of their oil money for Alaska or put an Alaska tax on lower 48 oil? A glut of oil other places does not benefit Alaskans in the least. You mentioned what happens to a town when oil leaves, now imagine that on a statewide scale. It’s happened before. If I remember right in the 80’s oil crash 7 of 9 Alaska banks went belly up, people just dropped house keys off at the bank. Last number I read was 322,000 working adults in Alaska, with a state the size of Texas, Cali, Montana combined. You can’t tax 322,000 people enough to pay for that large an areas costs. The amount of villages that need service, rural law enforcement, road maint, you name it costs a lot. Imaging a city of 700,000 paying to maintain 14,000 miles of roads, hundreds or airports, flying law enforcement hours for calls, etc etc. the state NEEDS oil revenue.
Alaska has little chance at manufacturing due to shipping costs, small chance at technology relocating. Alaska has tourism, fishing, hunting, oil, minerals. With double whammy of virus and oil price drop, it’s going to be a rough few years.
