> There is zero question that the Second Amendment was created as limit on the federal government interfering with individual states, and did not bar any state from whatever policy they chose for themselves.

Amendment 10, brought into force at the same time as amendment 2, says that the states can't infringe upon the right to bear arms either. That is very far from "zero question" as you stated.

> Amendment 10 [...] at the same time [...] says that the states can't infringe upon the right to bear arms either.

No. Just no. The most-charitable interpretation here is that you're confusing the 10th with the 14th, and that one was a century later.

The 10th does the exact opposite of limiting states! It says states continue to have all powers they didn't specifically give up by joining.
