> it's so easy to get an HD DRM-free copy of pretty much any movie
To a techie. The amount of people who find torrenting too confusing and overwhelming or are afraid of legal consequences or don't even know it exists is, once again, the vast majority (unless we are talking about Eastern Europe and third-world countries).
Even if you could prove that the US had, say, 10 million people that torrented actively (which is, honestly, a big stretch in my opinion), the pitch to movie studios is that they should abandon DRM because 10 million people can bypass it and 320 million people can't; and 320 million people don't even know the DRM is there or something they should care about. Not a winning sales pitch there.
