"Therefore, if what you say is true, you are literally nobody."
And guess what? That can really happen. If they identity thief replaces all your history with his own AND convinces the rest of the world that his is real instead of yours, down to the birth certificates and all, then how are you going to prove it was yours to begin with without getting locked into a "he said, she said" problem. And before you say close friends or family, you could be estranged and not have any real friends, plus the thief can convince them YOU'RE the thief.
