You keep making up stuff and attributing it to someone else.
Stop.
As getting government out of marriage at any point would not ensure that government would stay out of marriage voluntarily, I would be perfectly fine with very succinct amendments to state constitutions saying
“Marriage is a private contract between one adult man and one adult woman, binding only upon the one adult man and one adult woman who sign it. All terms of that private contract, including ownership and control of income, property, and other material wealth and sources are to be decided upon by them. As with any contract, the terms may not include any otherwise illegal action.”
