That’s funny, when I first learned about the equivalence principle, my first thought was “of course!” I have always found it to be very intuitive. The great leap is being able to frame it that way.
I worked on the early iPod scroll wheel, before there were advertisements for it and it was in common use. I found the UI interaction odd and unintuitive, particularly the "menu" button and the dead end you hit when "playing". Of course by the time the demonstrator ads came out and everyone was talking about how easy it was use, I'd already spent 10s of hours on it, and it WAS second nature. Being first and embedded in the culture of the time has huge UI advantages.
(Note that the HP Chipmunk 9836 also had a scroll selector wheel in 84)
Most people are UI bigots. Once they get used to a first something, they expect everything to work that way and hate learning anew. They get stuck on keyboards, mice, trackpoint nubs, trackpads, trackballs, scroll wheels, or touchscreens and refuse to move on. Of course there are 'objective' performance tests for each including Fitt's test of accuracy and latency, as well as, cognitive load. I guess once you have a hammer, every screw looks like a nail.
So I'd be a bit careful with the "of course!". It may well be obvious only because that is the first mental model you latch onto.
