Your main argument is “Learning QM shouldn’t change your behavior”. This is false in general. If your parents own slaves and you’ve been taught that people in Africa live horrible lives and slavery saves them, and you later discover the truth, you will feel and act differently. Yet you shouldn’t expect your life far away from Africa to be affected: it still adds up to normality.
Some arguments are convincing (“you can’t do anything about it so just call it the past” and “probability”), but they may not be enough to support your conclusion on their own.
