I genuinely see the point you're trying to make, but fitting a bicycle is like fitting an article of clothing. It's is laughable to suggest clothing be one-size-fits-all the same way it is for bicycle geometries. It doesn't compare.

In any case, you can make a bunch of different official sizes.

They already override plenty of individual preferences that people might have with their bikes.
