Main caveat I would make to this is that ALL women need to be kept in diapers regardless of status. Otherwise it kinda defeats the point of this thread. I'm fine with a caste system of responsibility for women. Those that prove that they can accept their place in society and contribute can be granted some additional responsibility but they still need to be kept in diapers 24/7 and generally treated childishly so that they are constantly reminded of their true nature. That's where the power structure comes from. Sure, it makes sense to grant some level of power to intelligent, and well-behaved women. Give them some authority over various 'baby' women for example. But at the same time they should never forget that they are still pooping their pants and getting laid down for a diaper change right alongside all the more infantile women that they might think themselves 'above.' No matter how much authority society allows them, they are still considered large children by the standards of civilization.

I absolutely agree that the best way to handle something like this is with a skewed sex ratio. It just makes sense.
Having an excess of women means that even low status men can be accommodated and higher status men can have a harem of women of varying levels of responsibility. Have a 'mommy' caste women to help you run the household and your harem. And have a few 'baby' women around the house just to look cute and as personal playthings. Choice of reproduction is up to the man's preferences.
Also, I think you answer your own question with the fact that women need to be cared for, but if there's an excess of women and they share household duties, the ones who are capable of doing so are just constantly on diaper duty when the man isn't around or doesn't want to. Although I'd change diapers for fun, sexual gratification, and to occasionally demean some women, it's also a kind of fun idea to come back home to a bunch of women in full diapers, pinching my nose, pointing to the nearest 'mommy' or 'sitter' caste woman and saying, "Yeah, this is much too stinky for me to deal with today. You get to work on changing everyone's diapers in here. I'm going to have a beer and play pool. Good luck! It looks like you've got your work cut out for you. Haha!" Then leaving with a grin while they groan in resignation and start pulling out diaper supplies.

Sounds like you just fantasize about not having responsibility

and being cared for. Which is one of the most common ABDL fantasies.

I applaud how detailed and autistic this diaper worldbuilding is, and I legitimately mean that as a compliment. I haven't dived into your DeviantArt yet, but the thing I'd probably want to explore in that is the propaganda and advertising side of things in a world run by two diaper manufacturer megacorps. Giant Blade-Runner esque billboards with women in ridiculously oversized Pampers? Rampant online conspiracy theories trying to convince the world that potty training was just a myth and humans have always been reliant on diapers? etc.
