Whether you call them overlords, representatives, bureaucrats, etc, lack of any sort of governing authority is the antithesis of a "society". Outside of living as a hermit, established rules of conduct are required to ensure functional relationships. The only questions are: What rules? How are they enforced?

Definitional pedantry aside, name 1 relationship that couldn't be severed due to horrendous behavior by 1 party or the other.
