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)".
The steelman opponent of the fence is "I see a reason not to have the fence, and any benefits to having the fence is outweighed by the benefits of removing the fence."
By contrast, the Chesterton's Fence argument is that there are unrecognized benefits of the fence. In practice, this easily devolves into an argument about the relative costs and benefits, but that is probably a distinct argument.
