The artificial womb will help advances in feminist laws. They will make it possible for so many more to do so much more. However feminists are not just going to stop there. Every victory they attain simply will give them more power and courage to fight no for the next issue.
An artificial womb won't have the ability to equalize pay between genders. It won't end street harassment such as catcalling. It won't end rape, or threats of rape. It won't end decades of misogyny, it won't end medical discrimination, it won't do anything other than make creating a baby easier. In short, an artificial womb won't suddenly result in an enlightened society. Feminist laws will still be needed.
