I mean, even for c9w who are easy tier2, you don't get to see them in action a lot cause they usually get knocked around r32-16 in most tourneys. Most female pro teams don't get enough game-time, experience or exposure as esports is still a largely male-dominated space. Female-only tourneys help popularize the names of female pros, and help organisations scout out talent, and encourage more women to get into esports in general.

Eventually, in a perfect-world, we wouldn't need such exclusive tourneys. We can have female pros as experienced, trained and popular as male pros and we can have co-ed teams and such.
