You try so hard to come across as if you had a remote clue about the UX field, yet you want to debate one of the most basic premises?
May I suggest to review the standard works (you have them on your shelf, I know you do);

Somehow you must have forgotten, well, everything, since you last read them.
That's okay, happens to the best of us. However, you might come across a little less unarmed if you could at least memorize the title of Krug's book.
Thanks for playing anyways.
