“I imagine it’s difficult as well if you are a wife and your husband asks you for something that you might think would be very dificult for you”…or just plain wrong or harmful.
Also, see upthread my example of my husband repeatedly keeping me from going to bed. It was hard for me to stay up when I was falling asleep on my feet, but stayed up with him anyway, because my husband told me to. He, meanwhile, didn’t realize that he was causing me a lot of distress.
I think that’s actually not uncommon among spouses–to not realize how much pain one is causing. And unfortunately, a “strong” submission program can exacerbate the problem, because it can choke off important spousal communication.
Here’s a post by a Protestant woman talking about how taking a too “strong” view of wifely submission hurt her, hurt her family, and hurt her marriage:

It’s a very dangerous area to approach without nuance.
It’s interesting that you mention the child’s obedience to the parent. There are some important disanalogies and analogies. For instance, the child is usually only under the parents’ full authority temporarily, until they achieve independent adulthood. After that, the child ought to honor the parent, but is not bound to obey. (And even in their minor years, they are not bound to sin just because their parents tell them to.)
Also, in modern society, children may be removed from the parental home if parents are cruel or neglectful.
Also, good parents recognize that (barring disability) the children that live under their roof are there only temporarily and ought to be on the road to complete independence. There should be a program of gradually increasing responsibility and independence, so that by the time the child has reached majority, they are able to function effectively on their own.
Consider, also, the fact that minor children are generally not left alone for substantial periods of time. Meanwhile, a wife and mother needs to be able to function without her husband, be that for a day, a week, a month, a year, or forever if he should die.
Also, Casti Connubii specifically says that wives are not to be treated as permanent minors.
