Interesting article and very actual topic.
The best example of homeschooling would be in my opinion the one we find in the movie "Captain Fantastic" with Viggo Mortensen. Have you seen it?
And the worst... the real story that came up last week in US: https://www.theguardian.com/us-news/2018/jan/17/parents-tortured-13-children-no-oversight-california-home-school
no, i haven't, but I will search what it is)
the article is shock.. even Russian mass-media wrote about it. craziness.
I guess that even homeschooling needs a little bit of supervision once in a while...
