Chesterton's Fence is about a technology somewhere between thousands and tens of thousands years old. Fences are extremely well understood. All of software has been around less than a century; the concept of personal computers running software that an end-user might adjust settings on is about sixty years old; thinking about Internet security is roughly thirty years old; the modern web ecosystem is no older than JavaScript, 22 years old. You're still right that blindly changing settings is not a great idea, but the Chesterton's Fence analogy is misplaced.
