> Treating all these scenarios as a single thing that you can hold a single, consistent opinion about suggests to me a lack of familiarity with its wide spectrums along multiple dimensions. I'll give it a shot: in all these scenarios, there ought to be a minimum standard-- backed up by the state-- to ensure none of these children are being abused or neglected. Public and private schools benefit from the children having to be around many other people every day, some of whom are teachers and administrators who have a profession obligation to report such things. AFAICT there is no common standard to enforce this across the myriad concepts of home school you mention. There obviously should be. Importantly, none of the "very dissimilar" concepts of home schooling you mention obviate this need.
