"girls are under the authority of their fathers and then their husbands, by natural law."
What makes you think the "natural law" supports patriarchy?
"Anthropological, archaeological and evolutionary psychological evidence suggests that most prehistoric societies were relatively egalitarian, and that patriarchal social structures did not develop until many years after the end of the Pleistocene era, following social and technological developments such as agriculture and domestication. According to Robert M. Strozier, historical research has not yet found a specific "initiating event". " I got that from Wikipedia, you could also look at The Origins of Sex Differences in Human Behavior by Alice H. Eagly and Wendy Wood
Even if it was "natural"
Do you hunt via persistence hunting or forage for your food? Agriculture is very unnatural
Do you only eat raw food? The domestication of fire isn't natural
Do you ensure that you are perpetually as physically fit as possible to defend the women under your 'authority", ie, as you are now, could you fight off another aggressive male? Who knows what natural predators could be round the corner
Invoking the naturalistic fallacy is never a good idea
