I am satisfied with the fact it would legally complicate immensely how to deal with marriage and those who violate the contract's rules - It is already hard to regulate a marriage between two people, let alone between three or four - Whether people like it or not, culture affects the law and society's values determine what's legal or not. In Muslim societies it makes sense for people to get married with more than one person, because it's how it works and they like it - But you can't forget that legal systems in Muslim countries are different from the CommonLaw and the Legal/civil system.
As I said before, for Commonlaw systems it might be easier - I am used with working with the legal system highly influenced by Roman Law, and one of the predominant aspects is the overwhelming (and sometimes excessive) codification, so everything is mostly decided according to what's on the law and not by legal precedents and jurisprudence - Most things are detailed in the law and the law is influenced by the culture you live in. A society that values family very highly will have strong family laws that allow for greater bonds and keeping more patrimonial assets, a society that values bodily autonomy highly probably allows for the consumption of at least some light drugs - The list goes on. There is no compelling reason to legalize poligamy other than "it makes people who want it happy", and marriage isn't about happiness - The number of divorces disproves that actually. Gay marriage is different because we are fundamentally discriminating against someone because they have a different sexual orientation, but nothing else changes legally and if gay people have biological kids trough technology or adopt, the law is exactly the same - Institutions can be changed, but when they are changed to the degree it can mean anything and it becomes indistinguishable from other contracts, then it's not worth keeping.

Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you
