As you say, the government already has that information, so while people might not be happy about that, it does seem a semi-reasonable way of confirming age. But the current plan is the reverse of that, with the government asking companies to conform age using a third party, which not only will definitely be using it for advertising purposes, but is more likely to get hacked, and all the information make it into even worse hands.
The problem with a ban in response to poor parenting is that it just disincentivises both the parents and children who have been doing it right until now, because if they’ll lose access all the same then what was the point of doing otherwise until now. And what would be the point of doing it right in future.
As do many people, but there are plenty others who will see this as being punished for doing the right thing, and will be less inclined to do so going forward. Whereas if this was addressed properly, it would continue to incentivise people who need that nudge to keep doing the right thing, whilst also pushing those less inclined to do the same.
I guess what I’m getting at is, this is just a terrible way to address a legitimate problem. Which seems to be the way this government operate.
