First off, if you found those population differences they wouldn't be usefully predictive when it came to your actual employees. The effect sizes are too small and other individual factors much too large.

Second, those differences wouldn't "justify" anything, they would only explain that a disparity would exist in a perfectly just world.

Mainly though, you say "of course there are gender differences" when that's literally not an acceptable thing to say publicly right now. Especially as a corporation. And the evidence showing irrational sexism and racism in tech is even better than the evidence around sex differences.

The question is how to tell how much each factor contributes, because one we want to correct and the other is just a part of the human condition. Since we can't ask the question right now, that's probably step one.

As to just letting the market sort it out ... I find it completely unconvincing that that would ever work. I think that's a naive view of how culture, human social organization and human rationality work. Not even mentioning the fact that serfdom and slavery are very efficient structures from the market point of view.
