I'm confused. What's the age definition of child? 12, 15, 18? Does this mean its against the law for children to install an operating system? What is the penalty for a child doing this and putting the wrong age or just doing it at all? What is the penalty for a parent or guardian of the child that does this? What happens to the parent or child if the child circumvents this control? Will child services be involved? Criminal penalties? Of course the only way to know an adult is the administrator is to tie the users government I'd to the account. Could this be done in some zero knowledge anonymous way? Sure, but I don't think it's likely. This seems to be the thin end of yet another wedge. The trend seems to be to be that we should be identified and survield every moment of our lives. The question is who does this surveillance serve? How much access do you have to your government or employer's data or advertisers or educators or ...? How does their access serve you?

That's a very long list of questions, most of which you wouldn't need to ask if you spent ten minutes reading the law. And the rhetorical point you seem to be working toward is much less effective when more than half of those questions evaporate.
