Hmm. So the man has managed to “acausally reproduce”, fulfill his utility function, in spite of not existing. You could go further and posit an imaginary couple who would have chosen each other for the procedure—so they succeed in “acausally reproducing”, even though neither of them exists. Then when someone tries to write a story about the imaginary couple, the child becomes observable to the writer and starts doing some reproducing of her own :-)
