"natural order" argument reminds me how Aristotle describes a natural slave as "anyone who, while being human, is by nature not his own but of someone else" and further states "he is of someone else when, while being human, he is a piece of property; and a piece of property is a tool for action separate from its owner." https://en.m.wikipedia.org/wiki/Natural_slavery https://en.m.wikipedia.org/wiki/Natural_slavery "natural" does NOT mean good or that it is worth preserving.
