I don't think it was about him saying 'one button is optimal for all time always' I think a lot of it was 'this is a whole new paradigm for people who only know the typewriter, let's make it simple for them, down the road when people have adjusted to the simple case, we can make it more elaborate' Hell at the time when this happened most computer joysticks had only one button, or in the case of one of the popular joysticks at the time, three buttons that were all just wired to one input.
