I don't think it's insightful (sorry) I think it's an interesting thought but misguided.
An emotionally (or otherwise) abusive man won't be satisfied by the things outlined in this book because the whole system hinges on the fact that the man adores, reveres and cares for his wife. If you look at the hyper-religious variations which spout the same thing, (e.g. books like "Created to be his help-meet"), the description is that a man should love his wife "As Jesus loved the church". ie, he should put her first, far higher than himself, he should be literally prepared to lay down his life for her.
The glaring problem with the surrendered wife stuff is that it only works if the man is genuinely committed to upholding his end of the bargain. If he does, then perhaps it does work. When it doesn't, it opens women up to all kinds of abuse. This philosophy doesn't acknowledge that abuse exists or can be subtle. That's the glaring problem - and then you're trapped because the whole system is designed to make you dependent on him for some mind boggling reason. Abusive men do not care for their spouses. They are not selfless. They would not lay down their life for anybody but themselves. In fact, we know they often are more willing to lay down others' lives when they believe their own mere lifestyle to be at stake. It doesn't work - a person can't live like that without suffering some kind of erosion to the self (if you prefer less fluffy language, stress and anxiety disorders can be and are caused by living in abusive relationships and the effects of these things can be devastating.)
The coping mechanisms that abuse victims use to placate their abusers and keep themselves safe may look similar to "surrendered wife" tactics but they are not the same thing. It's highly dangerous to suggest anybody in an abusive relationship tries these techniques to improve their marriage. It's just likely to entrench the victim further in the relationship so that when the abuse escalates, which it always does, they will be less able to break away.
In fact neither the expectations for the men or women in these books are realistic. The expectations for men aren't even written down anywhere so fuck knows how they are meant to know what to stick to but from the impression I get it's some super-human level of codependence actually. It's very very clear that the people who write these kinds of things are writing from an idealised point of view and not really grasping the fact that humans are never that perfect.
