That is definitely a valid point. However, for me, on upright and fretless, intonation is number 2, after feel. Feel is something that really can't be practised in a traditional sense, so during my practise sessions, intonation takes a good bit of my time. I like to really focus in on what I'm doing, technically. I work on other stuff, constantly---but I make sure that the new stuff is in tune. Different strokes et cetra et cetra. Neither of us are right or wrong.
