As an analogy, felons have free-speech and every other constitutional right, but they can't own certain guns. Do you think the Constitution confers unfettered gun ownership rights, in a similar manner as other rights?
Do you think every Supreme Court, since the founding (gun regulation is that old), was wrong about gun regulation and the Constitution, and this particular Supreme Court was right?
That's not completely true - felons lose the right to vote. Historically being convicted of a felony meant that you had forfeit your life. According to the principle that "he who may do more may do less", the government that chose to spare your life could certainly impose any punishment less than death, including the loss of any right whatsoever.
It's worth noting here that past cases before the Court referenced the idea that blacks could be allowed to carry fire arms if citizenship (pre-civil war) was interpreted more broadly, and that that fact was a reason to restrict it. So, yes, the Court has certainly erred in the past ... multiple times. 2A has been recognized as an individual and enumerated right for a long time. It's somewhat an invention of modern media that it isn't an individual right, and lots of people have been summarily gaslit into thinking it has something to do with membership in a (state run) militia.
Worth even more noting that's a finding in Dred Scott and Clarence Thomas quoted it in his opinion today.
