Having SCOTUS make that decision would strip the right to bear arms from everyone not in the National Guard.

Only at the federal level - state and local rulings would still dictate individual weapons ownership for hunting, hobbyists and self-defense.

'The people' in the 2A never meant 'private individuals' but 'the people' as in the American self-governed body: the 'we the people' people. At a federal level, the 2A clearly is referring to protecting the state-level ability to organize soldiers during a period without a standing national army. It has nothing to do with hunting, or collecting, and the 'self-defense' argument in Heller is an absurdity. A federal mandate for allowing individuals to bear weapons of war tramples all over a states rights to choose what is best suited to their diverse needs.
