Can you come up with a hypothetical person that would serve as an example of someone who doesn't fit into that diagram? The only type I can think of is Type D - (neuro)Divergent, they reside outside the diagram.
people are not ridged
I already accounted for that. I said the lines separating them as grayscale boundaries. A sliding scale.
People are complex and breaking them down to a single point of difference ignores a lot about the person.

I agree. But you CAN break a complex thing into many simpler things, and simpler things into even simpler things, etc etc. Eventually you get down to a grain of sand. This is Ontology.
