I think I have to agree with Mad Hatter on this one. It's not like the law is out to forbid you from teaching your own children anything, but more the fact that a lot of parents aren't or wouldn't qualify to make great teachers, and that it's more for giving children the opportunity to socialise with others and learn things from people with differing opinions/teaching methods/the like, which is beneficial as well as opposed to restricting children to one single person's viewpoint and isolating them from others. On the other hand, it does have benefits in it's own rights, such as accelerated learning, because other children can be a distraction and you can gauge the pace at which your child can learn. Hmmm.
