I cannot do fractional reserve banking. And if I can't do that then I can't really create money. A bank can have a fraction of the real hard currency that others can spend in "reserve" (physical or electronic). I cannot do that, I cannot borrow you $50 and some other guy $50 if I only had $50.

So I dunno, depends on what you mean by money creation, but writing an IOU is different from what money creation is in the sense that most people mean. It is closer to issuing a bond, which is not really money creation.
