Homeschooling is a choice, and it works quite well for some families.
Those children,being educated at home by motivated and capable parents, are in the most ideal educational setting.
For others, it is impossible, and for still others it simply isn't the best choice.
For those children whose parents are too ill-educated, too sick, too poor, etc., then institutionalization is likely the only alternative. Orphanages are the "best choice" too for some children, but no one would claim that this is an ideal situation for them.
Of course, wintertime, sometimes your rhetoric is so extreme that I wonder if perhaps you aren't just trying to parody a homeschooler. Surely you don't expect us to take everything you say seriously? :-)
It is becoming plainly and "seriously" evident that homeschoolers shine, on average, both academically and socially. It is not "extreme" to state, that, if possible, this would be the best educational setting for almost all children. If their parents are incapable, then a less than ideal institutional setting will be necessary.
