in such diverse disciplines as anthroplogy,
sociology, and neurobiology seems to suggest that humans are hardwired
to be able to track and interact with groups no larger than 150
individuals. See Dunbar's Number.

Rhizome vs. Hierarchy
This is another essay from Anthropik by Steve Thomas on why the rhizome
organizational structure is more natural for humans.
key point, I think, is that the pattern of organization that we've
identified as tribal; or as rhizome; or as anarchy (I'll now use those
terms interchangeably) is the mode of behavior which comes most naturally to the human
species. Hierarchy is psychologically difficult to bear, and humans
only enter into it under force—the locking up of
the food supply.
Rhizome anarchy is in fact the natural way humans organize themselves
to live their lives and provide themselves with the things they
need—and you'll find that even in contemporary society, those resources
which are not “under lock and key” are all acquired tribally.
