For the government to intervene a problem in a society, at least following should to be taken into account:

- the problem should be clearly identifiable and affecting the majority of people in a harmful way

- the solution should be relatively easy and cost-effective to implement (we shouldn't confiscate and destroy people's property and capital by introducing excessively high tax- and/or monetary inflation policies, regardless of the severity of the problem we face, or take huge risks with solutions that might have severe negative side effects to other people)

- the benefits of the solution should clearly outweigh the drawbacks

- access to the evidence of the problem and the solution should be available to everyone.

If all of the above conditions are not met, then we shouldn't have government intervention.
