At one extreme you have Disney corp squeezing money out of copyrighted material they created/bought/licensed. On the other extreme, without any copyright, you have Disney corp squeezing money out of any material they can find. Copyright is a moat that works both ways. Without copyright, profit from art goes to the most efficient t-shirt screen printer.
Be careful what you optimize for. Clearly the thing you actually object to is Disney squeezing money out of things. Maybe just make that part illegal, and forget the copyright?
What's the happy middle ground?
