Exactly. DRM is usually there to make it difficult to do something that is illegal anyway. With music, it's just as illegal to copy (copyrighted) non-DRM music as it is to copy DRM-protected music. The reason the DRM is there is because people still share music, even though it's illegal. It's the same reason we put locks on our doors: if everyone were law-abiding law, we wouldn't need them, but we do need them because people do break the law. It's not about freedom at all -- it's about stopping people breaking copyright (and other) laws, laws which still apply even when DRM isn't used.
