"Who decides what is lawful, if not society?"
In the United States, our supreme law is the Constitution, which was determined by representatives of society. The Constitution was designed to be a permanent document, which is why the amendment process is so difficult. The Constitution clearly protects the right of private individuals to possess firearms for historically lawful purposes (such as personal defense, especially within one's own home), as interpreted by no fewer than two Supreme Court cases (DC v. Heller and McDonald v. Chicago).
Put simply, modern society cannot renounce what was declared (and is continuously affirmed) as a fundamental American right without a Constitutional amendment, as myself and others like Invictus point out continuously on this forum.

"Your description of the National Guard is exactly what defines paramilitary."
The National Guard is not considered a 'paramilitary' force by any source. National Guard and Reserve personnel are designated as 'reserve' forces for statistical purposes. SWAT team members, other militarized law enforcement officers, and militarized private defense contractors would be defined as 'paramilitary'.

Obviously, there are a lot more than 11,000 National Guardsmen in the US.
"The difference between a riot and revolt might be the degree of organisation, so both lie on the same continuum of political violence."
"It is the general term for all armed (including sticks as in Britain and Japan), whose purpose is the internal assertion of the law aka state monopoly of force."
It is quite rare for the National Guard to act in a law enforcement capacity. Their power to do so (at their governor's order) has historically only been used during cases of civil disobedience/chaos of a scope exceeding the capacity of civilian law enforcement (i.e. a riot)
Legally, the difference is not in the level of organization (a subjective measure). The size of the disorder is the determining factor. If the state government is no longer able to discharge its powers, the federal government declares a state of insurrection and intervenes accordingly.
"That said the choice of wanting to be able to use a high degree on firepower in those riots is a valid for a society. Doubting the necessity is just as valid. Idolising this choice as something natural or fundamental right to make democracy work instead is misguided."
I wasn't trying to highlight the decision or support/oppose the legitimacy of rioters. I was simply arguing that the National Guard should be employed as a first-line counter to rioting instead of an over-militarized civilian police force. I have no problem with National Guardsmen driving around in armored vehicles, launching tear gas, and making bayonet charges into crowds of rioters. But I have a *big* problem with civilian police officers having access to armored vehicles and military-grade weapons, especially when regular civilians have no such access. A Guardsman acting on his/her governor's orders is better trained, better equipped, and more likely to stop a riot than a civilian police officer, as shown by dozens of cases throughout American history.
"As far as I am informed about the debate, through it is FRAMED as a ban on guns, the goal is indeed to apply the same form of regulation to gun ownership as for people becoming pilots, members of security forces, etc. Also, in countries like Japan, Germany, France, etc. this is exactly how gun ownership is handled. There are special conditions of personality, training (you have a "gun owning licence" like for driving)"
In principle, I am not opposed to raising the standard to be qualified to own certain types of firearms, but I am concerned that such measures could be used to enact a de facto ban. I have long proposed (and advocated for) a progressive licensing system, in which the deadlier a firearm is (as defined by class and things like practical rate of fire and theoretical combat effectiveness), the more training is required to own one. For example, one could own a single-action revolver or double-barrel shotgun (excellent choices for home defense, but poor choices for a shootout) with no background check and no training, but one would require an extensive background check and extensive practical testing to own a machine gun. Also, I would introduce some sort of "accountability" law, in which a firearm owner could be held legally responsible for his/her firearm if that firearm is stolen and subsequently used in a crime; thus compelling firearm owners to keep their firearms secured when not in use.
"Some restrictions have nothing to do with the comparative lethality of a weapon per se but for the associated culture"
That, I am staunchly opposed to. There is a similar legal concept in the United States called the "Assault Weapons Ban". AWBs attempt to restrict certain cosmetic features that have absolutely NO effect on the lethality of a firearm, such as: Folding or telescoping stocks, pistol grips, bayonet lugs, flash suppressors, threaded barrels, and grenade launcher mounts. Under an Assault Weapons Ban, the popular AR-15 would be illegal, but the Ruger Mini-14 would be completely legal:

The first picture looks much deadlier, yes? Well, they fire the exact same round at a very similar velocity with similar accuracy. In other words, one is no deadlier than the other, but only one would be banned under an "Assault Weapons Ban"
"Apparently a lot of Americans deem the lethal use of a gun necessary more often than it would be objectively. This is the reason what I consider irresponsible."
This is a result of our self-defense laws. Most US states have what is called a "Castle [Legal] Doctrine", in which one can legally shoot/kill a trespasser with no warning. Property crimes such as burglary, robbery, home invasion, cattle theft, and trespassing are taken MUCH more seriously in the United States than in other countries. This traces, in part, to our agrarian/rural roots. In the 19th century, one could have very easily starved to death if one's cattle were stolen. Naturally, shooting cattle thieves (and other outlaws) was thus justified and even viewed as a noble public service.
This tradition of being willing to respond to violent outlaws with lethal force is evident in our laws (most of which have generous self-defense provisions) and in the fact that dozens of American lives are saved each month by the lawful and judicious use of firearms in self-defense.
