Yeah, that reminds me a bit of communitarism with its concept of shared values (well, there is "some" connection). The problem is that when the elders decide, everybody must follow their decision, however cruel it may be. It may be essential for the survival of a community, but I doubt it would work in a large society. The elders really care about their folks, their options of doing "politics" (in the pejorative sense) are very limited. But in a state governed by politicians the tribal system would end up in a massacre imo.
