Utterly ridiculous. Parents have a responsibility to supervise their children. This is clearly defined by law in most countries, and for good reason; children are not emotionally ready to exert self-autonomy. They lack the cognitive skills and experience to do so. They lack the legal ability to exert control over their property, to engage in contracts, etc etc.

Now should parents monitor every moment of their children's life? No. But they have a duty and responsibility to supervise their children. Children should be given expanding freedoms as they mature, but this (again) needs to be supervised.
