You can't use an EVF at foot or waist level either. That's not what I am on about. I have no issue with using the large back display, articulating or not, as a live display when needed. But when I want to use a viewfinder I want it to be optics, not a tiny screen in a tube simulating that view. And like @throwanem said having tactile buttons/dials available as no look controls is a thing a lot of people like to use over touch screens. I understand it's a personal preference and an increasingly minority opinion.
