I don't understand why it matters. LET Peter's program use
magic if he wants to. It still doesn't allow his program to
return a correct "yes/no" answer on pathological cases like
the one Turing used. And, he can't claim that those pathological
cases don't exist because he needs Turing's proof to do that.
How can Peter's program possibly return correct results
for a program that halts if it loops, and loops if it
halts? It might be a lot easier to convince him that
neither "halt" nor "loop" are correct answers, and that
answering "neither" doesn't disprove Turing's proof.
