Yeah it’s not the changing, it’s the expectation. My mom told me one “women don’t have last names”, meaning there is no matrilineal naming convention here. So basically she didn’t care about changing hers because it was her dad’s name or her husband’s, but found it problematic. Why does “family name” follow the men like that, when the kids are born to the mothers?

Needlessly Patriarchal is a good way to put it.
