For "trading up", why would you give your OP to someone who has a lower q than you do? If your answer is "Because you get another, higher, one; what happens when someone gets to the top of the ladder? Besides which, if there was no "one OP per guild" ideal, why would you give an OP to someone who may well start gunning for your higher OP pretty soon anyway?
As for newer guilds, as soon as they attack someone, they lose a potential ally (tho I can't see how alliances would work at all in this theoretical situation) and make an "enemy". Assuming they fail their attack, they stay without crystals - likely enough there's no reason for anyone else to give them crystals to lvl up with (they might come after you next) and the people they attacked sure wouldn't give them any crystals.
As soon as someone starts giving crystals to you, its kind of expected that you won't attack them. This is where alliances come in, and once you have alliances, you lose a dynamic GvG OP system.
