Here in Libertopia, some people send their kids to a neighborhood school. This is a good method for people who think they don't have the time or competency to be responsible for their kids' education. (In most cases, this is not really the case, but people are free to choose.) These "neighborhood schools" range from something that looks like an old-style "public school" (without the coercive funding and mandatory attendance) to just hanging out in a group with a local curious character. And everything in between.
I suspect that most people, however, self educate. A lot of people choose to home school, with a major fraction of those "unschooling". Unschooling is just living a normal life while learning what you are interested in right at this moment. In most cases this results in the best education possible.
How many people are living each particular method? I don't know. It is nobody's business, so no one has made any study of it, as far as I know. What I do know is that there aren't too many ignorant, illiterate doofuses wandering the streets of Libertopia. And that's in spite of the damage from "public (government) schools" in generations past that can still be seen in some families, even now.
Of all the echoes of the State that are still affecting Libertopians today. only environmental degradation rivals government schooling in magnitude of damage still being felt. The learned stupidity and helplessness that came from the government indoctrination camps called "public schools" will be reverberating for generations. At least the cancer is now gone and the body can get on with the business of healing.
Most people have already moved so far beyond the old ways that there is no stopping them now. It's exciting to see what people with unchained minds have come up with, and will come up with next. These are exciting times- and not in a bad way.
