Playing “devil’s advocate” does not mean one is actually, honestly, personally, seriously advocating for the devil. Oral arguments are a time for exploratory & rhetorical questions - they are not a final verdict.
If the Founding Fathers intended the state or the militia to have the right, they would have said so. They didn’t. They said “the people”, which does not equate to the state or the militia; overlap, maybe, but not equate.
If they wanted to protect the right for self defense and hunting, they certainly would have protected it for "all persons" or "all individuals" or at least "all citizens". They didn't. They protected it for "the people" who comprised less than 20% of the population, leaving 80% with no protected right to keep and bear arms.
Why would they do that? Seriously.
