Copying a piece of paper isn't stealing.

Edit: Actually, now that I think about it, you might have to steal it to make the copy. Your analogy is useless for this argument. Money might be an abstract concept but bills and coins aren't imaginary. Try an analogy with digital currency then maybe there be something to talk about, but I'm guessing anything you can come up with will actually be talking about "hacking" or "fraud", not "stealing".
