Encouraging generic drugs eases the problem a little bit. Right to health care should be in the constitution instead of right to own guns.
There is no individual "right to own guns" in the Constitution. When the second amendment talks about the right of "the people" it means as a collective. It's talking about curtailing the Federal government from restricting states from raising state militias. But we don't have a state militia anymore, it's been replaced by the National Guard. There was no serious jurisprudence to interpret the second amendment as an…
You’re correct to identify “the people” as the key phrase, and you’re correct that the second amendment is referring to a collective right. But so are the other amendments referring to “the people.” The constitution is talking about a whole society, not individuals. E.g. the fourth amendment guarantees a society where “the people” aren’t subject to unreasonable searches from police. But that collective right also protects the individual. What applies to the collective applies to its individual constituents.
This makes sense in the context of the 2nd amendment: militias were “bring your own firearm.” The collective right was enforced through the individual guarantee. There was no need to interpret the second amendment in the past because it really wasn’t unclear what the framers meant. Some of the key figures in the Supreme court’s recent jurisprudence on the second amendment were prominent liberal academics like Larry Tribe and Akhil Amar. Here is Larry Tribe talking about how he changed his mind on the second amendment once he started seriously researching it: https://hls.harvard.edu/today/why-i-changed-my-mind/ (scroll down).
Your strongest argument is that the second amendment only applies to the federal government, not the states. That’s clearly true, but that’s true of every other amendment as well. The first amendment’s Establishment Clause clearly was intended to prevent the federal government from interfering with established state churches, or creating its own. The “wall of separation” phrasing wasn’t used by the Supreme Court until 1946. (Ironically, it was quoting the individual views of Thomas Jefferson, who also believed we should overthrow the government every couple of decades. With guns that every individual was entitled to bear!)
I’m willing to entertain the view that our whole incorporation doctrine is non-sensical, but that cuts more broadly than I think most gun control advocates would like to go. Moreover, the notion that the 14th amendment was meant to apply the second amendment to states is far better supported than the incorporation of the first amendment. Disarmament of freed slaves was specifically one of the concerns at the time: https://www.encounterbooks.com/features/racist-roots-gun-con...
