Marriage and Limited Liability Company Law
Marriage is essentially like any other partnership arrangement but with one major, very important difference. SEX is part of the marriage contract. You are "contracting for sexual services" when you accept the State's default marriage terms. The fact that Sex is part of the marriage contract is the main reason why the State is "concerned" about who it permits to marry.
Since States are more or less sanctioning a contract for sexual services between two people, States of the United States have traditionally attempted to regulate what kind of sexual activities are permissible in a marriage. Today, a lot of these old laws regulating the sexual activities of married couples are no longer enforced. However, a few of these laws are still on the books in some States.
If you eliminate SEX and THE STATE from marriage, you are essentially left with a Partnership, a partnership like any other partnership.
