The interest of one trade might conflict with another’s. In such cases, the absence of rules hinders liberty. Shared rules coordinate diverse activities and provide order and a well-functioning symbiosis.55 Not all rules require a rule-maker; rule-making is often spontaneous and decentralized. People interact with others and observe which actions have worked for mutual benefit. Subsequently, they self-sort, form hierarchies, and adopt effective practices and mutually understood rules with little deliberation and centralized decision-making.
