I think it is difficult to defend "copying" someone else's work without using some fairly iffy logic. For instance, making an argument about renting being similar is not justification for the act. Meh, maybe I am wrong. I have copied other people's "intellectual property" before. Sometimes I feel bad. Sometimes I do not. I make a copy of The Three Stooges shorts, and I do not feel bad. They are dead and cannot profit from their work any longer. I make a copy of Star Trek, and I am potentially dipping my hands into the pocket of the creators (studio, actors, writers, etc.). I make a copy of a reality TV show, and I am an idiot.
