The discourse on this issue is way overfocused on elite athletes, imo. Elite athletes have different reasons for pursuing their sport and are up against the upper limits of what their bodies are capable of. The real value of sports for the vast majority of people is in the exercise and community, and their performance is largely dependent on skill, not their genetics. Most people don't pursue a sport, but we would all probably benefit a lot from one.

Unfortunately, the discussion re: elite athletes is causing restrictions on trans athletes to be introduced at amateur levels and even among child athletes, where the competitive concerns are completely irrelevant. Given how important sports and games can be for motor learning, creating situations where kids are excluded or otherwise made to feel uncomfortable in athletic spaces is doing them a lot of harm.
