What's depressing to me is just how self-serving all this is. The original bill was AB 1043. Who supported that, breaking with other tech companies? Why Meta of course [1][2]! Meta likes this because it pushes liability onto the OS providers. Guess who doesn't have an OS? Google's support is a little stranger given Android. It seems like AB 1043 also shifted liability to third-party app developers instead of the app…
In jurisdictions taking the California approach Meta does not need to ask for anything like that. Their app just has to ask the OS, which reports the age bracket that was entered when the user account was made on the device, and the OS gets that information from whoever set up the account. The OS trusts whatever is entered at that time. No driver's licenses or passports or face scans or videos are involved.

...and this is pretty much the way to do it with the least impact on privacy and anonymity possible without first building up some high tech cryptographic infrastructure that would likely include hardware requirements that would, at least at first, exclude users who do not have an iOS/iPadOS or Android device that has a secure hardware element.
