I am not sure that this really changes the situation. The fact that peopke do use guns in defensive situations do not meant that this is the best option. I would expect most of those situations to be armed robberies, and there an obvious alternative is just to give the attacker what they want. It is painful and traumatic, but likely less so than killing them, and likely more cost efficient.

There are places where attackers "shoot first and ask second" (I heard that Sao Paolo is like that), but even there carrying a gun is likely to put you in more danger than it helps.

I think the main problem with gun ownership is that there is a feedback loop: the more people own guns, the more likely it is to be held at gunpoint at some point, increasing the appeal of carrying a gun. It is hard to break, no question. But it is possible. Australia was similar to the US not so long ago, and they managed to change it.
