Wow. This is shamefully elitist. No, you did not need to go to university to learn those two things. There are plenty of people that have learned them from other life experiences. Also, some of the worst code I've ever had the pleasure of reading was written by people with graduate degrees.
I myself didn't graduate, because the allure of starting a company was too strong. Here I am 20 years later advising people with degrees. If you are dedicated enough and creative enough (in the hacker kind of way) you can become skilled in just about anything you want.
However without a degree there are doors that are closed to you. For example the UC system will not even consider you for an MBA if you don't have an undergraduate degree. Don't even bother applying. Other private institutions will consider you but you need to be absolutely exceptional to get in.
I use that just as one example. People with a degree (especially a good degree) can stroll into an opportunity that I have to work 10X harder to to get. That said, once I'm in I tend to outperform my peers simply because I'm used to a world set on "hard mode" at all times.
Another thing I'm lacking are the deep friendships and connections that people who have a degree seem to have. That, to me, is the biggest loss from skipping a degree. Despite significant effort I don't seem to be able to make that part up.
