I wouldn't trust NFP unless I'm actually fine with a pregnancy if it happens. But for me, I don't find avoiding sex at the most fertile days of my cycle attractive and holistic - it's when I'm most interested in sex! So it's not chemically altering my body to avoid consequences (and possibly killing your libido in the process), but it is altering what would make sex most satisfying for me to avoid consequences (and again, my partner has no negatives).
I think one of the hardest things for feminism to manage, reactionary, radfem, liberal, all of them, is that due to our vulnerability to pregnancy and the demands of caretaking, in most situations, the house always wins.
You want more committed providers for trad wives? You get more women financially trapped in abusive relationships, or dumped for a younger model and left penniless in their old age.
You want financial independence and access to well paid work? You get a man who will happily allow you to pay your share of the bills while letting you shoulder all of the housework.
You want the social shame of bastardry to keep families together? You get women forced by pregnancy into bad marriages, or giving birth in secrecy and shame with the child taken away.
You want the very reasonable provision of not being disowned because of a pre-marital relationship? Men will no longer see marriage as a precursor to expecting a sexual relationship.
Every gain for women easily is translates into an equivalent gain for men. I don't know how, or if, we have an easy fix for this.
