That a law like this is even necessary seems absurd to me. A child learns by doing, by making mistakes by itself. By being curious about the world. By feeling the consequences of ones actions. Of course parenting is needed, but much less restrictive as it apparently is. My parents sent me to the UK when I was 12. i knew no-one. Yes, there was a school and a host family that fulfilled my basic needs, but I had to become selfconscious and responsible. I would never want to miss that. Your parents won't always be here and the earlier you learn to get on by yourself, the better. A child must develop a sense of self dependency IMO.
