The revocation list means nothing when they can get ahold of someone’s older sibling’s ID and sign up for social media.
Did everyone just forget what it’s like to an ambitious kid who wants to get online?
Do people really think a platform that needs people to jump through these hoops and use this imaginary international ID architecture is feasible?
Does anyone really think that kids won’t just set their location to Estonia and/or use a VPN to circumvent all of this?
Revocations are not for the individual ID but if an exploit is found compromising the IDs stored on a trusted element. Your older siblings ID can’t be used to sign for millions of accounts - just those who the older sibling lets borrow their phone that has their ID (and assuming there isn’t some kind of uniqueness cookie that can be used to prevent multiple accounts under a single ID). That’s a much different and more manageable problem (fake ids via older siblings have been a thing for forever).
No, this line of reasoning deserves nothing but absolute contempt when it comes to laws. We are not talking about getting the finnicky API to work at your job. Too often laws have had unintended consequences as a result of loopholes or small peculiarities. If the damn law doesn't even work on a fundamental level then it should be opposed on principle.
If there is no risk involved, everyone will jump on doing it.
That only covers large-scale reuse. It doesn't cover lending your id to your younger sibling if you want to, or if they find a way. Maybe that should be acceptable anyway. Same as you can lend your phone or computer to someone to use "as you", or you can buy them cigarettes and alcohol. Your responsibility.
If the zero-knowledge proof doesn't communicate anything other than the result of an age check, then the trivial exploit is for 1 person to upload an ID to the internet and every kid everywhere to use it.
It's not sufficient to check if someone has access to an ID where the age is over a threshold. Implementing a 1:1 linkage of real world ID to social media account closes the loophole where people borrow, steal, or duplicate IDs to bypass the check.
