On one hand-side - yes, you're right. On the other - right now you have a choice of not seeing the movie at all, or maybe seeing it correctly in the next month thanks to this key.

One step at a time.

Also, there's a whole industry around copy-protection which won't go away in one day. Pretty much the best we can do right now, is make is obsolete by proving DRM is useless, while they will try to prove otherwise. DVD-s right now are a nice compromise where they did their job™, and we get the content as if it was not locked. (of course you still cannot skip the intros on "official players", but that's just an education issue - for example mplayer can play the movie itself without the added marketing crap)
