The thing is, working life isn't only about using your particular talents to their best advantage, it's also about being able to communicate your brilliance and get along with others, and a whole host of other things.
IF you can be bothered to turn up every day and sit through a three year course without taking an axe to your coursemates and learn a load of shite that is unrelated to your specialist subject, and can then deign to answer some questions maybe even write a few essays, that surely is an indication that you are more likely to work as an effective member of a team, than someone like me, who MAY work very well in your enterprise or may not bother to turn up at all, depending upon how I feel on the day.
That's a big part of why paper qualifications matter. They show that you can put up with crap in order to get what you think you want. Nowadays with the student loans thing it shows that you are so keen to "work for a living" that you will even indebt yourself whilst undergoing this process..
OF course, that makes life really sucky for some of us, but them's the breaks. Of course how you personally deal with the joy or disappointment of grown-up life speaks more about who and what you really are, than whether you did or did not pick up a bit of paper, or "get the money" etc.
