When a casual passer-by records, copies, and disseminates, no physical aggression is committed. The enforcement of copyright law depends on a third-party initiating a threat of force against property, freedom, and life to dissuade such actions.

Copying is non-violent, whereas preventing it requires violence. And where does copying end, and thought begin? If I examine source code, or lyrics, or a short story, reflect on them, talk about them, and use what I have gleaned, haven't I copied them to some degree?
