I never found the the wordplay arguments from anti-gun types very convincing. It seems extremely clear to me that the 2nd amendment, like the rest of the bill of rights, is about conferring individual rights. We can thank the pointlessly flowery language employed by the Founding Fathers for this tedium.
The context of the Bill of Rights is a debate between federalists and anti-federalists regarding the powers of centralized government. The First Amendment, for instance, says "Congress shall make no law." States made laws restricting the speech of individuals, establishing churches, and so on.
We have every reason to believe state and municipal governments had the authority to protect public safety, which could eventually include restrictions on arms. If states did not want to restrict arms, then they could go that route as well. The irony is that "originalists" now use the federal government to invalidate state and local laws. This runs contrary to the framers' intentions. What's the rationale? "Well, if armed citizens are using guns to commit crime, kill each other in private disputes etc., and as a result local governments restrict individual firearm ownership, then the states are just not going to be able to raise militias for our common defense." It's transparently silly, especially after the War of 1812.
Collective vs. Individual is a digression. Civil liberties are limitations on the government, and the Bill of Rights is about restricting the federal government.
As far as my browser can tell, The Articles of Confederation mentions "militia" one time:
No vessels of war shall be kept up in time of peace, by any state, except such number only, as shall be deemed necessary by the united states, in congress assembled, for the defence of such state, or its trade; nor shall any body of forces be kept up, by any state, in time of peace, except such number only as, in the judgment of the united states, in congress assembled, shall be deemed requisite to garrison the forts necessary for the defence of such state; but every state shall always keep up a well regulated and disciplined militia, sufficiently armed and accounted, and shall provide and constantly have ready for use, in public stores, a due number of field pieces and tents, and a proper quantity of arms, ammunition, and camp equipage.
The "flowery" old-timey language is clearer here than in the Constitution. "Well-regulated" is not government regulating the oil industry: it means well-disciplined/trained/equipped.
The Second Amendment probably primarily modifies Article II of the Constitution, which reads, "The President shall be Commander in Chief of the Army and Navy of the United States, and of the Militia of the several States, when called into the actual Service of the United States."
