Always worth putting things in context:
"Section. 8.
The Congress shall have Power To lay and collect Taxes, Duties, Imposts and Excises, to pay the Debts and provide for the common Defence and general Welfare of the United States; but all Duties, Imposts and Excises shall be uniform throughout the United States;
...
To provide for calling forth the Militia to execute the Laws of the Union,
suppress Insurrections and repel Invasions;
To provide for
organizing, arming, and disciplining, the Militia, and for governing such Part of them as may be employed in the Service of the United States, reserving to the States respectively, the Appointment of the Officers, and the Authority of training the Militia according to the discipline prescribed by Congress;
To exercise exclusive Legislation in all Cases whatsoever, over such District (not exceeding ten Miles square) as may, by Cession of particular States, and the Acceptance of Congress, become the Seat of the Government of the United States, and to exercise like Authority over all Places purchased by the Consent of the Legislature of the State in which the Same shall be, for the Erection of Forts, Magazines, Arsenals, dock-Yards, and other needful Buildings;—And
To make all Laws which shall be necessary and proper for carrying into Execution the foregoing Powers, and all other Powers vested by this Constitution in the Government of the United States, or in any Department or Officer thereof."
"Section. 2.
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; he may require the Opinion, in writing, of the principal Officer in each of the executive Departments, upon any Subject relating to the Duties of their respective Offices, and he shall have Power to grant Reprieves and Pardons for Offences against the United States, except in Cases of Impeachment.
... "
(emphasis added)
You can argue about many things, but it is very clear that the militia was always understood to be an organized and disciplined organ of the government, under the control of the Congress and the President, and not a self constituted group. Indeed, the duty of the militia was specifically to suppress the actions of such groups. And that is how it was used on several occasions. Today, the various Militia Acts provide the justification for the draft.
The idea that the militia was intended to participate in an insurrection against the Congress, when both are "regulated" by Congress, is silly. FWIW, the United States did not have a standing army, or navy for that matter. The Constitution still prohibits appropriating funds for the military for more than one year.
Now, for giggles, research George Washington's comments on the utility of the militia and why he favored a formal army. The problem was that people did not want to be in the militia, at least not when there was work to be done at home.
