It's as if you don't understand anything.
Or are just being wilfully ignorant.
Men and women exist in humanity (and other mammalian species) purely for reproductive purposes.
Although, some people are born with disorders that make them unable to breed. Even though the rest of their genetics say that they're still male or female.
However, that does not mean that a fertile (or even infertile) male gets to call itself female, or vice versa.
And intersex conditions are too rare to really count them as anything but unfortunate.
