That would still be irrelevant for the game, it would only be relevant for the traders. The game would still work exactly the same if the model were that you would go to WotC with a specified deck, and they would print it for you, at a standard cost per card, or even if they cost more for more powerful cards. It would kill the trading, of course, but that's entirely unrelated to the actual MtG game.
