It’s a bad movie that you might have seen before. It tends to show up whenever an advocate of voluntary cooperation explains how society could operate without state coercion. Right on cue, the zombies from “Night of the Living Statists” rear their heads and mindlessly intone, “But if there’s no government, who will build the roads?!”
The zombies can’t hear your response, so it’s useless to try to give them facts and explain how things could be done in a way that’s better for everyone if roads and other such things were provided as private services rather than as coercive government monopolies. For those who are open to the facts, though, is there any evidence that people can actually cooperate voluntarily for their own interests?
As a matter of fact, there’s quite a bit of evidence of that.
