“Let them know better on their tiny plot of land and let them leave us to know better on ours.”

In general, I’m with you on this (especially what you say about the authoritarian tendency of many people). With regard to our separate small plots of land, it gets a little more complicated if my tiny plot of land is on the river upstream from your plot and I decide to make a pig farm or a coal mine. So the only way a “live and let live” philosophy works well is if everyone else is committed to it as you are. And that requires us to have live and let live as a basic collective value (which is usually so obvious to everyone that it doesn't even need to be stated). No priests or kings are needed to formalize and enforce that value. English common law evolved essentially from the process of neighbors working things out together over many generations. It can be done. Unfortunately, once the process is formalized by creating a sitting legislature to endlessly spin out laws, things go to hell. As the cliche goes, no one is safe when the legislature is session.
