My point was that it takes decades until the point you responded to becomes invalid. Even if Biden banned all guns tomorrow, it's likely that criminals will keep having guns during the life span of everybody alive today.
Yes, it seems like the gun issue in the U.S. is cultural. You couldn't make the same arguments for gun ownership in the U.K. or Japan, because gun ownership was not as strong a part of the culture the whole period since their founding. It took two mass shootings in the span of a decade for the U.K. to ban almost all gun ownership.
I would prefer if nobody had guns (as an unrealistic utopian ideal), and if people were disincentized to obtain them illegally. But repealing the Second Amendment is both a lost cause and would do more harm than good. There is no undoing centuries of cultural propagation and convincing tens of millions of people who have already accepted the idea to cooperate.
If I wanted to minimize my chances of encountering gun violence as much as possible, I'd have to move overseas.
