Because, of course, Terry didn't want to write the book that way. He had a lot of things to discuss, and your rather obvious but irrelevant question wouldn't have allowed him the room he needed.
I've just finished re-reading Unseen Academicals for about the 4th time, and although I didn't like it much at first, I found it much better this time. I still think that Terry tried to develop too many themes in this book for it to be one of the great ones, but then given the fact (or in my interpretation) that it's the valediction to the wizards, it may indeed be the best of the wizard books.
