That might be true if the supply of women's trousers were a monopoly - there was (and could only be) one company that made them. If that were the case then you are right, that company would have no incentive to add pockets, because women would have to buy pocketless trousers as the only ones available. That's why natural monopolies tend to be heavily regulated.

But the supply of woman's trousers is not a monopoly. There are lots of companies that supply them. If you were right, and there was an unmet demand for women's trousers, then there an incentive for one of the many companies that supplies trousers to supply them with pockets - because women would buy that brand over the others. If that happened than the other brands would follow suit.

That is the case - a quick google shows lots of results for women's trousers with decent size pockets.
