That is a false characterization of the discussion.
The specific claim is the low supply or even total lack of women’s clothing with bigger pockets is a reflection of the desires of the market as a whole, not specifically about pocket size, but the entire garment being purchased. This claim is because making and selling women’s clothing with bigger pockets is trivial, so the deduction is that the sellers have experienced insufficient demand if they are not offering it.
The other option is sellers have not picked up on an opportunity to sell a more competitive product, which might be true if buying tastes have changed.
I think you can add another criteria that certain commenters here have revealed. They usually also say that they do not want to scour the web for a pair of pants that has larger pockets (see example comment https://news.ycombinator.com/item?id=38000006). This means you also have to add convenience to the list of criteria.
I would classify small startups as more inconvenient which might in part explain why they struggle to fill this niche.
It's worth making clear that "convenience" in this case is really more like "not expending relatively large amounts of time, energy, and money".
Characterizing that as "convenience" seems demeaning to me, unless we also consider it a convenience that I don't need to fetch my water from a well or light a fire to take a warm bath.
Convenience was the closest word I could find to express it at the time. Maybe I should have said accessible instead. I did not want to imply a positive or negative connotation to it. I thought it useful to expand the list of criteria to add that women will also value the level of accessibility.
