Well people can find joy in what they want. To me, having an Elvis autograph is cool. Having an Elvis impersonator sign "Elvis" on something isn't an autograph, it's just an oddity. And having an Elvis impersonator hand me a card that has an "Elvis" signature printed on it isn't quantitatively different. The act of pen to paper for fake name doesn't make for significance, and I guess my imagination is sated by just interacting withe the character. But lots of opinions make the world go round.
