Are you so certain about that? You think things like standards (weights, measures, railway guages, etc.) can happen without some sort of central negotiation? You think poor places with lots of bedbugs are going to be willing to ban substances like DDT just because folks on the better side of the tracks want to? And if they won't, will DDT be eliminated from the environment? Do you suppose that roads will be completed when they reach the end of one "territory" and bump into another? Why?All good things that we now have, we could have without government, and it would not cost as much.
I wonder how carefully you have thought out this "no government" thing.
