Okay, let's say a copy is (essentially) free. So what? There are plenty of things that people buy where marginal cost of production is << than the price.
Concretely, why is selling a DVD with a marginal cost of production of $0.50 for $15.99 ok, but selling a movie with a marginal cost of $0.001 for $15.99 "special and different from anything that came before"?
