I'd consider it a good lesson. Learning at this point, when it isn't real money, that taking on loans can make your life very, very difficult is a good thing! It's not that they are teaching them that they are just a part of life--they want to teach them what happens when you DO make them a part of life. Seeing the impact of big loan payments and seeing how interest works when you're a teenager can strengthen your resolve to not take on debt when you're older and the money is real.
We had a similar lesson when I was in high school and it made a big impact on me. I think I was always inclined to live frugally anyway, but seeing how credit card debt worked (and this was back before credit card companies became really evil) made me steer clear of it well into adulthood.
