Say: I go to the store (whatever store it is), and buy GTA6 for $80 or whatever it'll cost (haven't bought a new game since Diablo II expansion was new).
The difference is I buy it (as in, the way we used to buy games, where that physical copy just worked, and once they got to the online activation thing, there was typically a way to activate it off-line) to what we have today (I "buy the game for the physical copy price, but am in fact _renting_ it long-term until such time the company deems the game 'old enough' and flips the switch).
If I'm not buying a copy of the game to use for as long as the disc still works (even if it has to be multiple discs), then I am in fact, not _buying_ it... I am merely renting it long term, and when I pay money for it, that should be stated plainly and clearly (and, I don't want an $80 empty jewel case... couldn't I just take a slip of paper to the register and fill out a thing at the register (to get the activation code on the receipt or maybe have the receipt contain a code you enter on the website and they send you a letter with the activation code _(and, either one includes the preset game deactivation/shut down date)_.
