What if the government (because I cannot say "we" when referring to "it") was the one who had to enforce copyright protections?  Burden of proof would change from "we have your router's ip address and want $20,000/song" to "we've created a government agency to uphold our country's already existing laws and arrest you", thus reducing the need for the MAFIAA to sue grandmothers for millions of dollars.  The resulting agency would take up so many resources and so many tax dollars that it would eventually be perfect, restricting all forms of fair use to what they actually should be.  But of course, the motion picture and recording industries would never want that, they'd lose their main source of revenue.
