Disclaimer: I'm mostly posting this because I know there are many "trad-con" and/or RP types that believe that being a housewife is still a good idea for women in 2021. I used to even believe this myself until recently. However, I think even angriest of feminists and trad-con/RP men can agree on this one, or at least find middle-ground...

Firstly, there is nothing "wrong" with being a housewife IMHO, but the fact is that, other than childbearing, the job has become obsolete due to modern technology and conveniences. You can literally order everything, including groceries from home now and never leave the house. Furthermore, any and all single people that work fulltime do all of these housekeeping duties in their spare time, both men and women. Do any of them have trouble keeping it up? I don't think so. Almost all housekeeping duties that were done even 20-30 years ago have been modernized through automation, technology, appliances, etc., or simply outsourced (such as the aforementioned Amazon example).

The Elevator Operator example for a man is self-explanatory to anyone that has used an elevator in the past 30-40 years - there is no such job anymore. For those that don't know, this was a legitimate career (or at least a job) up until the 1970's when elevators were modernized to what we know today. So, on its face you can see how ridiculous it would be for a woman to claim to be looking for a man that is an Elevator Operator in 2021.

Lastly, the one notable exception IMO for a SAHM (stay a home mother) is for when the child or children are very young - from birth until age 3 or 4. Children are developing their brains for their entire life during this crucial time and need their mother (and father, really) present. However, I am not a Child Developmental Psychologist (my GF actually is), so I won't pretend to know this subject well.

TL;DR - if you are going to marry or even just cohabitate, your partner should financially contribute to the household. Yes, even if she is raising your children. If a person does not financially contribute to the household they are a dependent, not a partner.
