Biological productivity = amount of living matter produced per unit area. You need to look at the oceans as well as the land.

Umm... you seem to be saying that nomadism is a preferred life style? Weird.
Why would you think so? Don't want to get into a long discussion, but just look at the differences. On the one hand you've open space, natural surroundings, varied food available for the hunting & gathering, which takes a few hours a day, the chance to do different things every day. On the other hand, your typical urban dweller of those days crammed a family into a single room, and survived on a sparse diet of mostly grains. Even into Shakespeare's time and later, streets were often open sewers, the air was full of smoke & stink, disease abounded. The great majority of people worked long hours for little return beyond survival. Humm... seems like some things haven't changed all that much :-)
