Personal opinion: As a teenager who likes school, 'unschooling' sounds bad. The fact that people would remove children from schools to learn by themselves sounds great, but what about math or biology or chemistry? Calculus you cannot learn from nature without reconstructing several centuries of work. Some people prefer to learn about how the world works, and the best way to do that is via school.
Now, it's not that not going to school makes you stupid, however, I think it deprives a kid from learning complex topics that cannot be grasped or learned by one self.
But of course, that's just me. You asked the Man, so I'll step aside
