That won't work, because most copyrighted material is worthless, and we can't predict what retains value in the long run, and most don't. Mickey is a rare example of value surviving to the point it was worth (in dollars) protecting. That's why I prefer a flat tax. 15% goes to the copyright/patent distribution system. Anyone can copy and profit off anything, but just pays 15% into the system. The system then pays out based on the rules and registration information. Public domain is then redefined as whatever is tax free. And, you can also buy anything directly from the government. Prices are determined by market value if it's a physical product. For digital goods, some rules may have to be defined, and maybe rules to define rules defined. Copies of songs could all just be 25 cents, etc. Books 2.99. But this is to own a copy (defined as having a copy on your system plus having paid for it). Just listening to a copy could be free. At least this is the direction I wish the world were headed.
