This is a bad idea. You want to impose a tax on people when they create something? Penalizing people for innovation is the exact opposite of what copyright protection is intended to do.
If I create something, and a corporation with deep pockets wants to take it from me, they can just keep upping their bid until the tax for me to keep it would bankrupt me, forcing me to give it up? No thanks.
