Nobody worked hard on making sure people could remove fences without understanding them ..., so this principle is not protected.

This seems false to me. I agree with Stuart's opening suggestion that democracy, free markets, and the Enlightenment more generally are in part designed to make it easy to dismantle historical patterns (e.g. religion, guilds, aristocracy, traditions; one can see this discussion explicitly in e.g. Adam Smith, Locke, Toqueville, Bacon). Bostrom's "status quo bias" also comes to mind.
