This largely matches what I understood as well. The only real difference is the prenup, which as I understand it will generally hold up if it's not insane and you throw enough lawyer time at it.

However: IANAL, and only did a cursory investigation when I was considering marriage. I do not know how much different states vary in their laws.

End result: I decided to not get married or have children under the current regime, and did an initial investigation on how to transfer and hide my resources to keep them safe should the situation arise.
