IMHO the main point of these schemes is to make it hard for adults to use social media somewhat-anonyously. So the government can more easily identify those posting 'prohibited speech'.
If there was a legitimate drive to protect kids from the worst of the Internet, there'd have been more of a crackdown on porn, gore, etc long before social media became such a big problem. And smartphones would have never been allowed in schools.
I'm very critical of all the schemes proposed but this is just a fundamental misconception on your part.
> If there was a legitimate drive to protect kids from the worst of the Internet
As with any disease, the impact heavily depends on virality.
The worst the internet has to offer to children, is not the gore or porn for the few that look for it (usually individually). The worst it does to children is the attention algorithm that captures practically everybody.
You already basically can't use most mainstream platforms anonymously. Try registering a Facebook without a phone number (you need to give a passport to get one in most of Europe).

Where are you from, because all of these things have/are being tried for a long time in the US (and, I'd note, received significant pushback from civil liberty advocates). Heck, TFA itself talks about how this social media ban is coming after a ban on phones in schools.
Gore already has been cracked down on. All the old gore sites like Live leak have shut down, Reddit has removed all the related subreddits, and governments quickly scrub the internet of videos like the New Zealand shooting.
What major revolutions or important political shifts have occurred from people anonymously shitposting on Reddit or Facebook ?
90% of the people that spout racism, conspiracy theories, threaten people, etc.. on social networks use their real name and login with their phone number, there's no need to ask the social networks to get ID cards, if you are the government.
Your argument hinges on the assumption that porn and gore etc. have worse impact on kids. I don’t think there’s a concensus on that. One might argue that porn and gore could have been found in print before the internet, but that social media have a more novel impact.
I personally like the theory that most kids problems are actually attributable to family issues. That kids in solid family environment/upbringing will not be “destroyed” by computer games, porn, gore (2 girls 1 cup anyone?), or social media. But that’s also just a theory.
