I think you grossly misunderstand all of the court opinions you are referring to. The Supreme Court has already ruled this is not a federal constitutional issue, it is an issue left to the people of the state. The ability to govern oneself also implies the ability to govern oneself poorly.
I am amazed at how many so-called libertarians on here really are in love with oligarchy when it suits their ends.
It's call "progressive" libertarianism.
