I think its a better than nothing kind of option for some families living in remote places or living very itinerant lifestyles
But in general, I think its just a way for parents to keep their kids as indoctrinated into their fucked up beliefs as they can.
Also, growing up I knew many homeschooled kids through boyscouts, and they were almost always socially stunted, and often intellectually behind because their parents were barely teaching them anything.
