Governments always have their own assault rifles and, usually, access to nukes or nuclear defense by proxy. By extension, they will have their own AI and we can only try to achieve some kind of parity with our own access to AI as citizens. Also, if there was a large personal incentive to own a nuclear bomb in a suitcase or something, wealthy people would probably hire personal security to carry one around. In the distant future, their spaceships will almost definitely have nukes or the equivalent. It seems like this all mirrors the weapons of war debate in some ways.
