Again, appeal to authority is a logical fallacy. If you tell me natural law, good, then the resutl in keeping with reason and evidence, even with a nod to tradition, wins. When the result is determined before the agrument, that is scholastacism, not natural law. The proof is how people respond. People igored Castii (which still has much good, but is dated and wrong on divorce and its vague references to marital chastisty) and actively defied Humanae Vitae. At some point, an inquiry is needed on what went wrong, where the answer is not automatically a wicked age or the devil. It is time for a few cultural and sexual discussions.

Playing an instrument under instruction is scholasticism.  A really good jazz club's performers are reason. That sounds so good right now, but they are already closed.
