Your points are well taken, and I would add that the revelation at Sinai also included a kind of sexual revolution: in contrast to all the cultures of antiquity, with their pederasty and sacred prostitutes and lecherous gods, the ancient Hebrews were instructed to restrict sexual activity to marriage with the purpose of procreation. It is under-appreciated how radically different the Torah was to the ambient cultures. Orthodox Jews are permitted some forms of contraception but only in the context of a family oriented towards children (and we still have a high fertility rate.
