While 99% true, there's an error in your position that if there are only male priests, there could only be a male pope. Being a priest is not a pre-req for being pope.

While someone does not have to be a priest can be ELECTED pope, once elected he would not only be ordained a priest but also a bishop. An elected layman only becomes pope upon ordination as bishop. Thus the impossibility of a woman becoming a bishop would disqualify her from being eligible for election.

Good point.
