Let me ask you this, do you think the concept of a role model is real?
Do you think voting matters? Do you think voting matters? A lot of people don't vote because they don't see their vote having an affect. A lot of women don't bother with getting to the top of chess or activities of equal to men because they don't want to bother being barraded by sexism all the time. The women grandmasters who beat the greats at chess, were they lauded? No, not as much as excuses were made for why the great men lost.
Another angle. Why should parents encourage their daughter to take up chess when there isn't an obvious path for the future. If it's only men then that leads to the thinking that women can't do it. The fact of the matter is the sexism in our history which allowed boys the freedom to practice what they want, be encouraged to do what they want whilst girls were encouraged to do things that mainly dads didn't want to do. Then those boys become dads and repeat the cycle.
Women's only leagues and tournaments are steps towards breaking these cycles. These institutionalized biases. It's not enough to tear down the wall, hand them a chess board and say off you go now.
