That sounds really dumb. I had thought that the blockchain could potentially allow me to buy and resell licenses without involving the publisher.
For instance, say I really like the Le Cercle Rouge, and own it in several digital formats.
A disc of the film contains an encrypted copy, and authorized players that know how to decrypt the film can verify that this is a genuine copy, and therefore I have the rights to view it in a certain region, blah blah blah.
I can sell that disc to someone else, and next time, it will be their player that mediates the license to view. Since I no longer have the proof of pwnership, I can no longer view the movie. (I am taking the legal theory behind the DVDCSS scheme seriously, rather than dismissing it as somethhing that is easily cracked)
Similarly, if I buy a license to view it on amazon, the player checks the license file, and decides that since I paid a certain fee, I am authorized to decode and view those bits. What I cannot really do is transfer this license to another, less bandwidth starved provider, or to a friend, or an ebay bidder. If ownership of a license was recorded on a blockchain, transferring licenses would not be dependent on the permission of the store that sold it to me in the first place.
