Game Disc use case - right to play on Blockchain

This idea has been posted before and isn't new, just starting the discussion again. It would be a perfect opportunity as Sony have just announced the demise of the physical disk. What if the right to play the game existed on the blockchain, you could trade the game just by transferring that token. It could work cross platform, you could just plug your keys into the console you're using or authenticate using it's native identity platform. Games have not been stored on discs for years but the right to play has been kept on them as a physical token to unlock the right to play. For me this is a perfect use case that cannot be forged or pirated. The contract is issued by the game company, it can be onsold this way, borrowed for a period of time under contact etc, use case is endless.
