So if everyone in my neighborhood has a gun, it's okay for us to all shoot each other? You're right, that makes perfect sense.
What I meant was that if I could shoot fireballs, and you could shoot fireballs, and everyone could shoot fireballs too, how would that be a unique trait?
The sword and elephant would certainly be unique in the real world, but if everyone has access to it, then how is that any different to, say, most people having a car?
If every single person could do what Napoleon did, would we remember him for who he was? No of course not. Just replace 'Napoleon' with 'shooting magic'.
And you are right, I'm nearly 16. That doesn't change anything I said.
