It does seem obvious that short of having your own copy of something purchased (in this case, a movie), this will happen. Purchasing the right to see a movie, listen to a song, on a service, will never be the same as holding a physical copy. I wonder if it's even legal for Apple to maintain a copy of the movie in iTunes for customers who've already purchased it once they have lost the right to host it. Clearly, most of us don't appreciate the difference between what it meant to purchase something, and what it means today in the digital, subscription world.
So, if you really want to own a movie or a song, buy a physical incarnation of it, or make a digital copy of it.
