That’s a great story to be sure, but even ancient people knew about intersex people - that’s where the original (and now often discriminatory) term “hermaphrodite” came from.

The reason people keep bringing genetics and chromosomes into this is because they’re the literal blueprints for our bodies. If its not encoded into the blueprints, our bodies cannot make it happen - and as far as humans go, there’s only two basal sex templates, male and female. That’s it.

Anything between those two states is fair game (as we see from intersexuality), but unlike with gender it is biologically impossible to not be on that spectrum somewhere. Thats not a “world view”, it is an empirical fact backed by decades of genetic research.

If you had the resources to go find and examine every human on the planet, I guarantee you that out of the 10 billion humans that exist on Earth, not a single one would fall outside that spectra. I’d bet my life on it a million times over.

Additionally, you really could not be more wrong about sex being a useless category. Your sex is one of the most medically significant traits you can have - at times even more important than your ethnicity in determining clinical outcomes.

I’m an open minded person, but I go where the evidence points to - and with all due respect, its not towards what you’re cooking.
