Resource scarcity is not the only thing that causes population to plateau. Human intelligence is a pretty huge variable here which allows us to do things like fulfill our evolutionary urges without producing children. I'll agree that scarcity causes population to plateau, but I don't agree that a plateau in population is inherently an indication of scarcity. It's rather silly to talk about hypothetical ecological populations in a void, when we can observe the actual populations we're trying to make predictions about.
