I agree with you, but I don't see how it matters in this context. The GGP implied that MIT students who don't protect their bitcoins "deserve" to have them stolen. The assumption by the poster seemed to be that MIT students would necessarily be technically savvy enough to protect their bitcoins. That's definitely not necessarily true since there's plenty of non-technical majors offered at MIT.
I think losing $100 given to you for nothing (comes from donations of alumni) because you didn't know how to secure it properly would be a very cost effective way to motivate someone to learn the basics or ask a friend for help.
Better $100 of bitcoin than your credit card information.
My assumptions are that (a) they're very intelligent, and at least have some technically-savvy friends, and (b) losing bitcoins that were given to them for free leaves them no worse off than if nobody gave them bitcoins in the first place.
