You seem more knowledgeable on these topics than I am. That said, I don’t agree with some of the portrayals of Christianity. “The imprisonment of our true selves”, “we are all intrinsically evil”, and “chastity/castration as a special mark of piety” seem a lot like the Albigensian (Catharism) heresy.
While not an official stance, I think the Catholic Church is in line with the hylomorphic thought that body and soul together are good. We are not just flesh and we are not just souls but the two together in one kind. That then flows into the idea of wanting kids/family and helping kids be good by helping teach and grow their moral intuitions (which is opposite to what wokeism thinks about reproduction)
“Goodness is submission, not flourishing” is a big claim as well. What does flourishing look like? I’d argue the goal outlined in life to know, love, and serve God leads to flourishing by helping us be saints. To seek to understand the metaphysically ultimate, to make virtue a habit, and to demonstrate faith by bearing good fruit leads to a flourishing society, no?
We are to be prudent in stewarding the world, not to condemn it. Creation is good.
