Friction is an important factor to consider here. With 0 friction, there's no need to actually "own" a game. You can just purchase it whenever you want to play it. Currently, the assumption is that anyone wishing to play a game will play the asking price, whether that's $60 or less. If you want to play AAA game du jour, you'll pay full price. What if you can sell your digital game, with no friction? Well, you pay your $60, play for a couple of hours, and once you stop playing, you tell your steam market bot to sell the game at market price +- your preference. Then, when you want to play again, you tell your bot to buy the game again. Rinse, repeat. This is not going to fit well within the game pricing model as we know it.
