If you play a land every turn and discrad another one to activate the emblem, you use 2 cards of your hand per turn. But you only draw one each turn. This means that you end up with 6 lands (on the play, on the draw 7) in play when you start your turn with an empty hand. If you play the land then, you have no card left to discard for the ability. If you skip an emblem activation (or two), you end up in a late game with more lands in play. Playing an 8-drop every turn is better than a 6-drop. Also, those skipped one- and two-drops become irrelevant often very quickly.
