You can sell the ticket, you can only watch the movie once with it though. So if i watch the movie sure I own the ticket, but if I sell it that doesnt mean somebody else can go watch it. You bought the disc your game came on and access to the game nothing more. Your disconnect here is you think you own the game and you don't, you never did. You just didn't understand what you bought or that all the money you spent was not for ever lasting access.
