Blockchain Digital Content Distribution?

[mr-whitekey]

Services like itunes, Audible, Amazon Kindle, Amazon Video, Steam and other digital content providers have you "buy" the audio book, movie, game or song, but you must use their network to access it. You usually can't trade it, give it away or even lend it.

What do you think of a blockchain based DAC which allows a more tradition role for digital content ownership? One which we would truly own what we buy, as opposed to long term leasing. Would there be enough demand for it?
