I get the playground line. But I really do mean something stronger. As a child, I may have asked why on occassion, but the most common question was probably, "why can't I play basketball?" or "why can't I play space invaders?".

I think you're arguing that children need to be stimulated. And I think this requires a fair bit of direction. And I think w/o a good deal of direction, most children will not learn things they need to. I suspect math and writing/grammar being two big areas that most children would neglect. Not all, but a huge number, crossing or approaching 50%.
