If you're missing this aspect, musical instruments (to take one example that I sometimes wonder about) can easily seem designed to be "hard" to use. Compare a computer keyboard, with its clear labels, to the (to a newcomer) totally opaque grouping of the keys on a piano.
Now, I still think the keys could be labelled without any threat to the possibilities of expressing one's creativity, but it's a bit less annoying, having read this. :)
I think part of the resistance you'd meet to labeling piano keys is that you're highly unlikely to be able to play well if you depend on looking at the keys, as it slows you down too much to be able to play anything but the slowest pieces, whereas you can write well (though arguably not type well) on a keyboard while still looking at the keys.
As a teaching tool, labeling can work for both, but as a crutch for people who are less than proficient, labeling does not work well for someone trying to play the piano. There's a greater need for getting to a certain level of proficiency if you wish to play the piano than if you wish to use a keyboard.
