So by my understanding, moon wives can function as an indirect social defense/weakpoint? As in, if you social someone with a moon wife into something that's against their best interest (from the view of the moon wife) she'll take action against that.
On the other hand, if you social a moon wife into thinking that something is in their love's best interests...
Here's the core thing about moon wives:
With them, it's love, for good and ill. When you own his heart, he loves you with all his heart. But it's "just" love. It's not a leash.
So how a moon wife would act in such a scenario depends on them, their love's personality, and a lot of other things. Oula is confident, power-hungry, and assertive, so would probably tell Rathan that things are being taken care of, give orders for people to go slow and delay, and then focus on re-socialing Rathan - or failing that, go call up Keris and tell her someone is tricking Rathan. By contrast, a less demanding, less connected moon wife might well just go along with their love's whims - because after all, their Love principle does make it easier for their love to persuade them of things.
But it's important to remember that what they feel is love. In 2e mechanical terms, it's an Emotion, not a Compulsion. And treating a moon wife as if they're a slave rather than someone who loves you and so needs and wants attention, care, and emotional reciprocity is a fast way for them to decide they're being taken advantage of, Hurry Home to their heart, and shatter it and them spend their time making you suffer (and eventually die) until their heart regrows and they can feel positive emotions and Compassion again.
