It's the correct idea but the way it should be done is by coming to a democratic consensus that helicopter parenting is bad, not by attempting to hobble the infrastructure of government. If only for the practical reason that it'll simply be outsourced and privatized. In US states where the police can't scan license plates, there's a private industry doing that and then selling the data back to the police. The same result but now you pay a premium.

Lee Kuan Yew was fond of making this point. Weak "horizontal" administrations will creep in ways that are more opaque and without checks than strong "vertical" ones.

But whatever age-verification solution I have seen so far sucked, really badly. And I can't believe people promote something like a government based age check. People need their privacy.
