That's a little backwards: something like the modern state might emerge from groups of people living in any number of ways. Clans/tribes don't emerge from the lack of a state. The state as we think of it is very recent in human history, after all.

Also you originally referred to the "problems of governance in Afghanistan" which I took to mean the warlordism, violence, suppression of women and so on. I was pointing out that these problems are more tied to the specific cultural and religious history of that area. If by governance problems you were instead referring to the strictly administrative or bureaucratic challenges you might encounter trying to, for example, organize a collection of peaceful worker communes, then I misunderstood.
