I think there is a cost. Maybe in an anarchic society, they would pay for a security company, but they can&#x27;t afford to pay for both public security (taxes for the police) <i>and</i> private security. Since they are forced to pay for the police anyway and can&#x27;t afford both, it makes sense to use their services even if they believe they are inferior.<p>Or perhaps they are trained in the use of deadly firearms and believe they can protect themselves from crime using that but they live in a country that prohibits firearm use.<p>The point is, sometimes we can&#x27;t act as if we already live in utopia. To reach utopia we have to get there from a place that exists in reality, not from a fantasy ideal world.
