As it stands, the world is mostly made for right-handed people, with a lot of accommodation for lefties.
In very lose terms, the number of people who identify as 'somewhere on the spectrum of gender' is about 0.5% - but this includes a huge amount of people who have a 'feeling' and frankly, are probably ideological about it, i.e. "I don't believe in gender, ergo, I refuse to identify as one".
The actual number of people who truly do not fit in essentially or pragmatically one or the other gender - to the point wherein they would feel uncomfortable going into either a male or female bathroom is extremely small. Remember that even most trans people actually identify with one gender or the other.
So, when > 99.9% of a population 'is something' ... 'it's normative'.
"Do you not think its noble to make life better for 0.1% of people?"
It's not within reason or pragmatism to change how everyone on the planet refers to gender - and our entire 'bathroom social norms' to accommodate a tiny minority.
Here is a practical, non-ideological solution:
It seems as though every edifice has to provide special facilities for handicapped people.
Change the sign on the handicapped door, to something considerably more generic, like 'a bathroom for whoever' - and then those who are not comfortable with male/female - or for any other reason - can use it.
Now the 99.9% have their bathrooms - and 'everyone else' who doesn't fit perfectly into that paradigm, can use the 'other' facility.
