There's just very few sports in which the male body is not at an intrinsic mechanical advantage.
When you come from the extreme tail of the bell curve that elite sportspeople come from, that small advantage becomes a large advantage. When you move the mean a little, the tails move a lot.
This doesn't just affect trans women but also intersex women. There's a definite tension in sport insofar as we expect elite sportspeople to be abnormal humans far from the mean. For males this is unproblematic: an abnormally strong male like Michael Phelps or Usain Bolt is still clearly a male.
But for females nature does not provide for us a clear line but rather a smooth gradient between female and male. The difference between an abnormally strong female and an abnormally weak male is not a line that nature always provides for us, it's a line that has to be drawn artificially and is therefore open to debate and challenge.
One plausible explanation I've heard for this is that while men and women have the same average mental capabilities, men have a higher standard deviation than women. There there are more outliers in both directions. Champions are found at the upper extreme.
