Chesterton's meta-fence: "in our current system (democratic market economies with large governments) the common practice of taking down Chesterton fences is a process which seems well established and has a decent track record, and should not be unduly interfered with (unless you fully understand it)".
Yes. I suspect that Chesteron's fence arguments are stronger in traditional cultures. Markets and democracies seem to have much greater self-correcting abilities, so the argument seems to be weaker (as long as you're not touching the key parts of the systems).
I don't know about that. If you (try to) remove a useful fence, the system might self-correct by removing you.
