As AI and automation trickle down to individuals as means of production are continuously decentralized, this includes firearms manufacturing. While today it is utterly simple to make a firearm with nothing but a few pieces of pipe and a nail, advanced manufacturing processes now being potential to individuals will completely prevent laws from preventing criminal possession of much better firearms.
The former has been possible for literally centuries, since the advent of industrial production of plumbing parts.
This is now able to be manufactured by individuals at home, without resort to plumbing pipe manufactured by industry.
It is obvious that advancing technology increasingly enables individuals to increase their power to possess firearms, and unless gun control advocates intend to prevent technological advance they will not be able to prevent criminals from possessing firearms of modern sophistication.
All gun control laws can do is render law abiding civilians more helpless and vulnerable to tyrants, thugs, and violent criminals, since only they will respect laws. Given the disadvantage being more and more helpless against such forces creates, fewer and fewer civilians will be able to survive obeying such laws as render them defenseless, and the overall effect of gun control laws will be to decrease the number of law abiding civilians, as they either resort to breaking the law to preserve their lives and property from tyrants, thugs, and criminals, or succumb to violence and die.
Personally, being well trained in the possession and maintenance of firearms, I strongly advocate early training and facility with firearms as the best means of security against common threats.
Nothing else is reasonable, or lawful.
