Yes, although I think a statewide law also would be too tyrannical for my taste, but I don't think we should fantasize about regulating something like this. Parents have to have some sense of responsibility for their children.States rights.
Suppose we decided to punish parents who forced children to study for long hours. We could. We could outlaw this practice. We could say they were torturing the children and were making them near sighted. It would just be stupid, because parents improve over time. They learn from each other, and there is no book or manual about being a parent.
