In Daniel Quinn's book, "Ishmael: An Adventure of the Mind and Spirit," he talks about the Taker and the Leaver cultures. The Taker cultures invented agriculture so they could stay in one place. The Leaver cultures on the other hand just moved from one place to the next picking fruit from the trees requiring no hard and difficult labor from them. In the New World, our cities are levitating and so we can move easily from place to place wherever Mother Gaia has provided us with her sustenance. If a late frost nips out the harvest in that area, we just move to where the weather was sufficiently balanced to produce the food ready for us to just simply harvest it. No more planting, cultivating, animal domesticating required.
