The model’s conditions matter. A resource with agreed rules, monitoring, and enforceable limits differs from unrestricted access. Before inferring inevitable collapse, ask which institutions exist and whose participation they recognize. Diagnosing a collective incentive problem also leaves open which remedy is fair, effective, and accountable to the people affected.
Use the reservoir example to separate diagnosis from prescription. Measuring each withdrawal may address one problem, while access rules and accountability address others. Privatization, quotas, and collective management can each change incentives, but they can also shift power and exclude users. A thoughtful application asks who depends on the resource and who participates in choosing the remedy. Avoid treating a vivid model of overuse as evidence that every real community has the same structure.
