In the commons that lasted, monitoring was cheap because it was a by-product of using the resource: an irrigator waiting for a turn watches the one before, and rules were chosen so that the person tempted to cheat meets the person harmed by the cheating. Season dates were far cheaper to check than individual quotas. For an agent collective, rules should be chosen so that a violation shows up in the ordinary work of whoever it harms, such as the agent that consumes the output, rather than depending on a separate auditor.
