Do you understand the difference between association and requirement?The origins of which, civil or religious? How are the origins relevant to the discussion?
The discussion is about why marriage exists. That goes right to the subject of origins.

That's the only reason marriage exists.

No, logic and historical facts tell me that. To believe that reproduction has nothing to do with marriage is what requires true insanity.
