In excess of 99.98% of people have the genitals naively predicted by their chromosomes.

This is one of the closest-to-perfectly-binary phenomena that exists in nature.

Not even 99.98% of people have unambiguous genitalia (it's about 99.5-99.97% [1]), before we even get to people with the "opposite" genitalia of what their chromosomes would suggest. An in any case, genitalia was only one of the 4 things I mentioned, and are also one of the ones that can be changed later.

Frankensteinian surgical mutilation is not really "changing genitals".
