I think the idea is "Liberation from set expectations", i.e. the MUST in "must be a in a provider". At least, that WAS the idea at some point, not sure it has stood the test of time, and modern rhetoric seems to have gone to a bizarre place.

The idea is that we should be free of societal expectations, and free to choose our own path, is liberation I can get behind. It is the part of the modern, western world I embrace and am happy for, that I am free to chose my own path. Neither I nor anyone else should be judged against a sense of universal criteria, because my happy life might be someone else's living hell, and the multitude of lifestyles possible is something I like.

Sometimes, I think all sides get this wrong. Feminism that doesn't value stay at home mothers who freely make that choice from personal preference is just enforcing a different norm, not a freedom from norms. Ditto the reverse and a view women should only be SAHM, or that men should be providers, or strong, or whatever.

I have no idea if any of that is possible at scale and, quite frankly, I don't care. I am going to live my life how I see fit, grant everyone else the same privilege, and let ideologues argue amongst themselves about what people should do.
