Arguments about marginal cost of production don't matter when the cost of enforcement is high. The issue of piracy ultimately comes down to whether agreements are enforceable. In the long run society won't help people enforce the unenforceable. If we come up with some form of technological fix that "knows" when an agreement has been broken then piracy will dwindle. Otherwise these laws will eventually be taken off the books, like adultery and other former crimes. That's not meant as an ethical argument. Simply a forecast.
