I think the time commitment is the biggest issue. Let's assume the costs are the same to me (perhaps due to employer subsidy): When I take a MOOC, I'm pledging at least 5 hours a week. That covers 2 hours of videos, 2 hours of homework and 1 hour of additional research / review. If I pledge 5 hours /week to a traditional class, I don't get nearly as much learning. I have to commute to the class, which is at least 30 minutes each way. Now my 5 hours buys me 2 hours of class, 2 hours of commuting and 1 hour of homework. I've lost an hour of homework and an hour of research. I know which one is better for me.
