You do not want to do away with compulsory education. We need some basics even if we never know when we will use them.

The biggest myth is that a teacher will appear when the student is ready. Teachers are not angels dropping out of the sky to save people. They are part of a production process that takes years to produce.

You cannot just tell everyone to take an online course or read a textbook unless you want to waste even more time figuring out that they have never trained to learn in a formalized process.
