You're trying to justify the dominant social mode rather than trying to discover arrangements that make people fulfilled.
Marriage stats suggest that humans aren't at all monogamous, most marriages end in divorce, and most people cheat.

2 is pretty key. The parent(s) are the anchor for the family unit. Examining marriage outside the context of family is a big conceptual mistake.
Uh, no. Monogamy is rooted in, basically, the following issues:
1) Germ control. You can get deadly diseases by sleeping around casually.
2) Sex leads to babies and human babies do best with two parents. It is a big burden and our species is designed to do the two parent thing.
3) It takes 15-20 hours a week to build and maintain real intimacy. There simply isn't enough time in the week to have lots of different genuinely intimate lovers. The math suggests that most people can sustain no more than two genuinely intimate sexual relationships.
