What is the point of marriage?

This is an odd question. Because I thought people knew what the point of marriage was. The real question is whether or not you desire marriage, not what is the point of marriage because doesn’t everyone know that?  

For some people, it’s due to spiritual reasons. For other people, it’s due to love and marriage represents that love to each other. For other people... it’s purely for conveniences, such as those young foreign women that marry those older rich men that they claim they love, or to get visas, or to get military benefits, or just any kind of benefits that you would get if you were married. Another point to marriage is cultural norms. I know no one likes comformity, even though many who dont like it follow it.But, that’s just how life is. When you fall in love, the norm is to get married. But, now that we have the most diversity that we have ever have had, we can literally do anything and be accept within some sort of subgroup. So, that’s good.
