Your analogy doesn't really work because you can't copy a gun. These tools are way more dangerous than a gun because you can replicate them very quickly. You can never destroy the tools once they are created, someone always has a copy.
This is what scares me more than nuclear weapons. A nuke requires a huge amount of people and infrastructure to maintain and launch. But a digital weapon? Pfft, copy that shit onto a USB key and one guy can wipe out power stations across the entire country.
