There are also many homeschool types in California that are exactly what the article is about. I had an unfortunate experience with a group of students at my performance arts center. I agree with you in that there are good elements of homeschooling co-opted to be used in bad faith (and permitted by a failure of our government), and similarly good elements of public school that are co-opted by the failings of our government.

Like you said, it depends on the state and the family, but the state is inevitably going to have some slip through the cracks. Add in a certain anti-type group of people and homeschooling is suddenly pushed as the solution to their interpretation of "whatever backward ahistorical pseudoscientific garbage is being pushed". The amount of homeschooled students who have anti-vax parents are way too high and it's truly a plight that doesn't seem to have active prevention, even in states where it's supposed to be better like in California.
