There's merit to the idea that college typically does not foster an entrepreneurial spirit, as the prevailing assumption is that you'll go on to apply for a job. Still, I think the author is seriously underestimating the value of going to college, which Steve Jobs' 2005 Stanford commencement address addresses nicely:
Of course, whether or not to stick around until you get your degree is another matter. But I'd argue that much of what you learn about the world, culturally, historically, theoretically, can be invaluable to entrepreurship.
If you count dropping out of college, and then attending only classes that interest you -- without being enrolled or paying -- as going to college, then sure. Of course that model of self-directed learning is quite opposite the usual cookie-cutter process where you are told which classes to attend and how many "units" of them you "need".
If everyone did things Steve Jobs's way, college administrators would have heart attacks. For the most part, going to college means jumping through the hoops they tell you to jump through, and they send you home if you don't take the prescribed courses in the prescribed timeframe and pay the prescribed fees.
