The fun thing is these early city states were _really tiny_.

Apparently distance wise at least it wasn't very hard to escape from the grasp of earliest cities and the place where you went - a days walk away - likely was not that different - "Assuming draft animals and carts on a flat alluvial plain, the reach of the earliest states for grain requisitions is unlikely to have extended much beyond a radius of roughly forty-eight kilometers"

Of course leaving ones home is probably a burden if you've used to sedentary life.

It's unlikely they had carts or draft animals yet. Domestication and the wheel were later inventions.

But there may have been primitive agrarian communities.
