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.

Death of classmate from past feels like a reminder to change my life
Arming teachers for safety likely to create gang that can’t shoot straight
Fear blocks us from experiencing reality deeper than physical world
Ruthless impersonal judgment is typical tool of cultural conformity
For me, Valentine’s Day seems to bring out my regrets every year
Like an alien, I move through a world I can see but never touch
To unlock your heart for real love, you must embrace vulnerability
Surreal dream wakes, shakes me; which is reality, which is dream?
When we feel we’ve lost control, our behavior stops making sense
