> making it just difficult enough to copy that most people will consider it not worth the bother
I don't think that the analogy holds up. The deterrence only applies to uploaders and not consumers, because the processes for removing DRM and distributing videos are independent. It just takes one person to make a video available to the entire world. It does seem like torrents are available for most of the Netflix catalogue, so I'm skeptical that DRM is useful for popular shows.
The analogy is good, but the reasoning is a bit off. Let me fix it - You still lock your door in the morning because you know that your insurance company will not pay out your theft insurance if anything gets stolen. DRM is mandated all the way up the chain (and noone really cares if it works).
