I explicitly stated that she didn't work and there were no kids. Premarital assets aren't relevant, legally or otherwise. And many women get married straight out of their parents house or college. My point was that there are plenty of cases where assets are divided unfairly.
What a retarded analogy. Even if you get officially married, it still requires your consent. You can agree to everything right up to standing at the altar and if you say, "I don't", instead of "I do", you're not married. The entire purpose of involving the state is to officially acknowledge that you do consent to the obligations associated with being married. There's even a "grace period" after getting married that allows for annulment in case you change your mind. Cohabitation alone is not consent to being married any more than kissing is consent to having sex.
I gave you links that show the history and purpose of "common-law marriage". The only "absolutely nonsense" here is your hand-waving after being shown to be wrong.
