What is the point of marriage?

Many things. As a personal pact it notifies society of it's presence. As a legal contract it affixes equal stewardship of chattel, equal right to health care decisions with marital issue, equal protection of self and mutual incrimination. And as a spiritual bond sets in record the fact of it's commision for all eternity and inspection by all interested future parties to the parity as one entity.

This is beyond the capability of most narcissists today and probably only means a bridezilla brag and arm candy claim but the profound nature of it exceeds their comprehension anyway.
