No, it won't change the amount of resources produced from the land at all. All of that hasn't even been figured out yet, so we will determine the amount of resources that should be produced from the land when we get to that point (soon!) and then work backwards to find out how much each type/rarity of plot should produce. So this would actually burn tokens without any inflation whatsoever.
