Obviously if 100% of students were free loaders, they just wouldn't offer the class so it's not a real option. Even then, you wouldn't have the assignment, the dissertations, the feed-back and I doubt the teacher will be as available.
A big part of the cost of doing a degree is the opportunity cost of not working anyway. If your university fees are 10k per year (not unrealistic in Canada), but you could be working a 40k/year job instead, the real cost is 50k/year so you would only really be saving 20%... 20% for the privilege of an incomplete experience, no testing to verify you grasp the concepts, no possibility of doing a masters and no diploma to show for it.
Roaming classes is like buying a Mitsubishi mirage. Sure, it's a car... but you can have a car that's twice as good for 20% more.
