Sure, there may be "varying degrees" of love (if it even makes sense to "measure" love). But why not have varying degrees of love for several spouses, just like we have varying degrees of love for several children?
Free will is an option for sure.
It may be that multiple partners is outlawed due to eugenics. In the sense that, over time, a sub-group of society who allows many mates may have an advantage wealth wise over those who just have the one mate.
