The 2nd Amendment only applies to the federal government. You are correct in that the federal government cannot ban guns in Massachusetts.

But the Massachusetts state legislature could, if they did away with Article XVII of the state constitution.

I aknowledge your argument, however, I'm not sure that I agree with it.
I'm not sure that I agree that a state, county, or municipality can legally ban guns. I know that some have done so but I'm not sure that it's legal.

I see nothing included in the 14th amendment that says the states can abridge the second.
