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)".
I see your point, but I don't think the original Chesterton's fence is a stable concept. Knowing why the person-who-built-the-fence, built the fence, is different from knowing why the fence was built (and allowed to stand). But, as you say, de gustibus (an expression I will steal from now on).
