There is a thing called the "network effect" where each additional thing that is added, such as a telephone, or a Twitter user, adds value to the existing network. This also helps to explain why vaccination is such a good idea. When you have lots of people immunised, you have "herd immunity"; where a disease can not spread because people don't pass it on - this also protects people who aren't immunised.
The widespread availability of guns in America, means that a network effect is in operation, even when you have gun bans in various place.
Incidentally, the 2nd amendment didn't give Americans the right to own guns. English law was in operation before the US Constitution was written and Section 7 of the Bill Of Rights Act 1689 said: That the subjects which are protestants may have arms for their defence suitable to their conditions and as allowed by law.
America went from a place which already had the right to one where the clause "suitable to their conditions and as allowed by law" was removed. America is mostly fine with that.
America has decided that about 11,000 people a year killed by guns, about 150,000 people a year injured by guns, and about 33,000 killing themselves, as well as the economic on-costs in health care, is an acceptable price to pay for freedom.
I think that's stupid. I married an American; we live in Australia because of that.

Sydney thinks of itself as the greatest sportsball team "of all time" but its fame doesn't extend that far because although people might have heard of Sydney, they only have a vague idea of where it is (and that includes people from the other side of Sydney). Its greatest rivalry is with the Melbourne Thunderstorms.
Kipper on the left; Purranna on the right. He is grey; she bites.
My sister found Kipper in the bins out the back of the supermarket where she worked; so we kept him because she already had a cat. We found though that he got lonely when Mrs Rollo and I left the house, so we broke Purranna out of kitty gaol.
