Simply because sex isn’t sufficient
As the *only* category, does not mean that it isn’t the most important initial category. And in fact, as everyone who hasn’t lost their minds knows, it is.
I’m not meaning this to sound hyperbolic, it’s simply the truth of what you’re suggesting; if boxers were separated by weight class and not sex, what you’d have is this; lots of dead female boxers.
