You'll still have societal pressures.

I mean, theres a fundamental cultural reason why a woman is given priority over a man in a custody battle.

Take away the government, but keep the sexism baked into the culture, and you have the same outcome, though, I don't know if it would happen in a court, you'd probably just get a bunch of sexist villagers trying to run you out of town because youre trying to take away a womans kids.

And you plan to remove this culture?
