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.

Barack Obama’s effort to imitate FDR’s ’36 campaign full of danger
The hole is always there, but I foolishly hope it’ll just go away
Norman Rockwell or Norman Bates? Holidays are dysfunctional for some
Nature’s renewal and growth boost my hope for my own life each year
Was life planned before birth? What did you come here to learn?
Advocating peace requires more than hating those who start wars
The pounding rain from the storm brought me warmth, light and love
Why does most love hurt us? Because one usually loves more
