I do. Well at least monogamous marriage. If you read the Stoic or Buddhist views on attachment, you might agree that monogamy essentially sets up a “single point of failure.” What I mean, is that you may be locked into a situation with all its legal baggage where you have no “fail over”; a practical monopoly wielded by whoever is more powerful emotionally or financially. That’s not to say it can never work because it does for many. It’s just not how I think the “critical thinker” ought to proceed. If you read the work of Dr. Helen Fisher regarding the addictive nature of “love”, doesn’t monogamy facilitate an “over exposure” to a partner as drug?
