I have to stop voting now. Actually, I had to stop voting yesterday, but.. I'm addicted! Anyway your comment is right on the money.

I thank whatever gods may be that no gummint agency has yet been empowered to replace neighbors helping push neighbors trucks. I think if that happens, I will get a bicycle, or a little red wagon, or anything I can push all by myself (without attracting too much empathy from the neighbors).

I do think a lot of the problem is how we are densely packed into cities, as @deirdyweirdy noted. Many studies (famously lemmings) have shown that the stress of high densities causes bizarre and dangerous behaviours in every species studied.

Your comments are perhaps the strongest advocacy for voluntarism I have heard. Frederic Bastiat and Lysander Spooner, whom I have had foisted on me of late, both make far more technical, but no more persuasive, arguments towards that end.

Thanks for your insight!
