The issue is woman would disappear from profesional sports. Sinners 16.27 rating means that he double bagels Sabalenkas 13.29 essentially 100% of the time. The 500th ATP player has a UTR of 13.81, half a point is quite a bit stronger, do he's still very much stronger than Sabalenka. You probably have to start looking well into the thousand somethings for something that is consisently beaten by her.
Only the top 200 players make money, the top 100 good money, and the top 50 ridiculous money.
UTR can also include unranked games if one of the players submits a score and the other approves it.
But it’s not just that. If there are no top women in any kind of leagues in chess, that will only further discourage women from participating competitively in chess in the first place.
Note that most competitive women chess players play in women’s only tournaments even though they can easily join open men’s tournaments as well. For various reasons, one being that these women’s only tournaments are where they have the best chance of winning or being in the top k for prizes.
But I see where our disagreement is. You think there ought to be more women in chess. I think different people can do different things, so women don't need to match men in every statistic and vice versa. If we open it up to universal participation and it turns out to be a male-dominated game, then let it be. I don't think there's anything wrong with that.
You don't have a say though, others want to see women play chess against each others and happily pay for and organize that event. Or do you want to make female only events illegal? As long as they are legal they will continue to be held.
