What is the benefit of having gender on government documentation anyway?

This is something I have been mulling over for a while and I think I landed on my thoughts on it, and I'm interested to hear others ideas.

I am moderately pro-trans. I think adults should be able to do whatever they need medically, kids should be able to do whatever they need socially, and the rest is all kind of a bigger discussion but that's a topic for a different post. All that to say I definitely fall to the left of the needle on the topic at large, if perhaps not as far left as many of my friends.

I personally think this EO about gender (the one that defines the sexes) is actually just a smokescreen to create activism fatigue and move the goal posts. It's the only explanation for it being written this poorly and un-enforceably(Sex cannot be determined at conception, boys do not produce gametes until puberty, and not everyone produces or receives gametes, so this one is doomed to the history books). And it's working. Lots of people are ignoring real issues because they're too busy lasering in on this one EO.

That all said, it got me thinking, like, what IS the right solution here. And moreover, why do we need one?

There's very few things that I think the government should be doing that include gender. There are no laws that I can see that should be enforced based on someone's gender. I am starting to believe that the best way to do this is to scrap the field entirely. Getting rid of the "Sex" field on documentation would make it so we don't have to have this discussion, ever again. I think the only thing I could think of conceivably would be affirmative action initiatives and, honestly I lean towards those being a poor solution to discrimination, I'd rather find a different solution. But I understand that is not necessarily a popular opinion among the liberal party.

I am, full disclosure, going to take this to the other side as well to see what they have in terms of arguments for or against having the gender marker on one's . will be interesting to see both groups ideas on this.
