For any given decision, letting individuals decide what they want does not necessarily lead to a great situation for the community. Climate change-related stuff comes to my mind. We are failing to take the right decisions, and have been for decades (in my opinion). I often see people say "let the market decide" as if it were the ultimate way of deciding what is best. It's often not in my opinion.

For the topic at hand I don't think there's a good way around letting people pick what they want to study among what is available. I deeply believe they should be able to decide what they are going to study for themselves and be given the keys to take informed decisions. Nobody can know better than themselves what is best for them.

You still need to provide a sensible set of available curricula, and people don't individually have the power to decide which curricula should be available so you still need an informed group of people to decide on this, not individually. Obviously you'll probably have to close curricula which don't attract enough people so you'll have some bit of market deciding.
