It is time to stop pretending that infinitely copiable works are like physical things. As Nina Paley would say, copying is not theft. If I copy your bike, you still have a bike.

It is time to insist on owning your music (or whatever other artform). Copyrighted works only have one owner: the copyright holder. Even if I buy the CD, I don't own the work; I only bought a license to listen privately until the CD wears out. Or if I buy the book, to read it till the book wears out.
