“Who will build the roads?” is the question that belongs at the top of every libertarian drinking game. If we didn’t have forced labor, the argument runs, there would be no roads. There’d be a Sears store over there, and your house over here, and everyone involved would just be standing there scratching their heads.
Related to this is the traffic light question. Why, you libertarians must oppose traffic lights! I have no idea why people think so. This question would be up to the proprietor. And yet the evidence accumulates that traffic may flow more smoothly without them after all.
