Feminist Utopia...?

I don't see that as an ideal at all. It's not equality - it's just that anyone who's different has been removed from society. Children growing up that way will never learn about the world. And I don't believe there will never be disagreements; people who live close to each other, by definition, will fight at some point. Everyone will be genetically different (apart from sharing the same race and gender) and so some people will naturally take more powerful roles, some will want to oppress others and to start wars, some will become serial killers. And when that happens, there will be no laws to sort it out. Sounds like the opposite of utopia to me.
