I don't think there's a good way to structure it in our current economic system. The only solutions I can't think of are more socialist or universal basic income. Essentially, if AI companies are going to profit off the creations of everyone in the world, they might as well pay higher taxes to cover for it. I'm sure that's an unpopular opinion but I also don't think it's fair to take an art style that a creator might spend an entire life perfecting and then commoditize it. Now the AI company gets paid a ton and the creator who made something super popular is out on the streets looking for a "real" job despite providing a lot of value to the world.
