You might also compare this with the traditional system of distributed dispute resolution that held sway in Iceland at the time of the sagas. While quite different cultures, many similar solutions and incentives acted to minimize violence between familial groups. In that case the system failed when it fell out of decentralization and into control of a sufficiently small elite for them to become a defacto government, but it took 300 years to reach that failure case.
