After hearing about this proposal for three months now, I still believe it's fucked up, especially the fact they don't even know what method they'll use, whether it's digital IDs (which will take likely at least a decade to become mainstream), facial scanning (authoritarian as fuck), or some other shitty proposal.
There's also the fact as a child I wasn't able to go out very much, so social media was useful to me, especially to give me time with friends digitally, and as a time burner, which can be detrimental for a child in a similar place to have it all banned.
In all ways this happens, this will either be extremely authoritarian or would not be necessary as all people set their birth dates to their exact one every time without any variation, like magic, as if that shit would ever happen.
