Marriage is about the codification of a baseline contract between a procreating couple. It is the states way of incorporating two people as a legal entity for ongoing and future legal treatment with a strong basis in custom. This is in the states interest as they like to say for obvious reasons in raising the next generation of citizens. Nothing stops spiritually sanctioned marriages between the non-procreating pair (or polyamorous). from living together. In fact these arrangements can be better served by boiler plate legal agreements that do not consider procreation as the purpose of the union.
