Maybe "non-redistributable" instead of "non-copyable." I don't disagree with your assessment, except I'd say DRM doesn't exist to restrict the machine - the goal is to restrict the user. Which is necessary, when users aren't trustworthy. But I'd disagree that DRM doesn't serve you a purpose. It serves the purpose of establishing trust and enforcing conditional exchanges of information. The alternative, like you imply, is no communication, or communication through a different medium that doesn't involve your hardware at all.
