Just think of how the revolutionary war was fought. It wasn't with a national standing army, but by state militias called into service of the federal government.

You don't need to explain what isn't in the Second Amendment.
It's not there ... It doesn't say or mean what you want it to mean.
A State can form, arm and regulate a militia without violating the individual's right.
No one is asking you to make something up that suggests otherwise, or isn't in the Second Amendment.

There is no individual right in the 2nd, no matter what Scalia twisted into Heller V DC. It's clear from the text " the right of the people" is used, not an individual reference.
And the case stating such right DC V Heller, ... well read about the problem for yourself.
This definition of “the people” applied consistently throughout the Bill of Rights, the Court said.11 In District of Columbia v. Heller12 in 2008, the Court approvingly quoted Verdugo-Urquidez’s definition, and similarly suggested that the term “the people” has a
consistent meaning throughout the Constitution.13 But Heller also said that “the people” “refers to all members of the political community.” Heller thus contains a confusing three-part analysis: (1) it approved of
Verdugo-Urquidez’s interpretation; (2) it substituted “members of the political community” for “persons who are part of a national community”; and (3) it suggested that “the people” means the same thing throughout the Constitution. Heller’s analysis has created a tension
that has attracted little notice
