It’s been many years since I’ve been in a classroom, but I feel like we could and should have a highly advanced system for individualizing education in a way that works with most learning styles.

I agree with your intent, but my point is underscored by the second to last sentence in your quoted text:

" I can code those algorithms in a program, and put that program on a floppy disk, and then we can mass produce that disk. We can make millions of copies of that disk and spread it all over the world so that millions of people can play my game. "

That person isn't going to do that for free. They'll likely expect payment (a reasonable ask) for the initial production, but also the ongoing support/update of the curriculum. All of those costs would be in addition to the resources spent on the lecture for the other student.
