If your fencing was done by idiots, then at some point you have no alternative but to start tearing down fences and see what happens. Chesterton's Fence implies either a degree of design or a timeworn quality that most software products don't match.
Chesterton himself was using it as a religious metaphor, and I think most of us agree that software engineers are not literal gods.
