"I think nuclear fission combined with fossil fuels is probably enough to last until we develop fusion or hydrogen based power."
Problem is there isn't enough usable uranium on the planet to make increasing the number of active nuclear plants viable for more than a couple of decades.
That, and a lot of what there is, is in places that make Saudi Arabia seem enlightened (Niger).
"Anyway, the reason there's been no nuclear plants built without government action is because it's illegal to build a nuclear plant without government action"
I think you will find that in most parts of the world, building power plants in general, not just nuclear plants, is done by the government, not by the free market.
