I think that the point he is trying to make is that the decision to reserve the priesthood to men was by God and not by human reasoning.
That’s probably true, but he should least give us some examples of real-life faiths were women become clergy and the faith still stands strong against things like abortion, ‘gay marriage’ to demonstrate that it is possible. Or even say something like ‘and my hypothetical created faith will reject these things.’
Otherwise it’s kind like saying ‘if I was going to found a country, it would be a communist state, they’ve always worked out so wonderfully.’
