10 USC 246 does not cover males under 17 or over 45, these are part of the People who are not legislative Militia. Hypotheticals are not evidence.

If Congress does indeed reinstate assembly to properly arm and equip every member of the People, I will promptly concede. But hypotheticals are not evidence.
