Agreed, mobility is perhaps the defining component of human success. The ancestor H. erectus, in many respects represents the first incarnation of the mobility that lead to hominid domination. Through an entomological argument of all things, it appears the H. erectus was losing body hair, that the advantage of being able to cool the body through surface evaporation of a very mobile and very durable hunter proved deciding. So, indeed, our mobility has deep roots.
But, even with that truth, the net mobility of us in our amazingly rapid migration was likely on an order of less than a kilometer per generation. Over the course of 15 or 20 thousand years we covered some ground. So, while I would rather not have to drag my plow half a mile, I recon I will endure.
