Of course it's technically possible to release a movie DRM free; that's a silly statement to make because like you said, it's not done legally. The music industry has decline dramatically because of choices made and the movie industry doesn't want to follow in the same footsteps. They have no reason to enable people to make it even easier to distribute movies and content either. Saying piracy already exists isn't a good enough reason for them to suddenly open the floodgates of removing DRM. I'm no fan of DRM, hence I rip my own content to bypass the reliance on it, but I also understand the reality of the situation. Feel free to protest in whatever way you want, but I wouldn't hold my breath over it. What you're asking for just isn't going to happen.
But hey, it looks like there is a new alternative to get high bitrate movies with lossless audio with digital distribution:

You're better off with ripping your owh movies off disc though...
