So this may well be true; certainly there are places where IT is incompetent and admin is...
unhelpful. However, as someone who has been IT and who went to a school that had a... "fun" time with wifi[0], I can assure you that letting just anyone run a wifi network can have some fairly nasty fallout when they all fight over the same 3 channels and nobody can actually use wifi at all. Further, unless the students in question are actually doing a computing program that includes wireless network as part of the curriculum, it's not part of "the education they paid for", it's a service that the school should be providing (and yes, in the case of finite shared spectrum, imposing a monopoly on). If it's a computing masters program that includes networking, then yes of course the school should arrange a lab environment where the students can mess around, and the above only applies outside of that environment.
EDIT: [0] Although actually thinking about it now, I think the primary reason that policy was enforced had more to do with that letting people set up their own WAPs would undermine the 802.1x userIP mapping and the security folks had opinions about that. Dorm wifi was a mess because the sheer number/density of clients was awful regardless, but allowing just anyone to fight over channels would have made it even worse.
