Just say that the government will control every single device that's controlled to the Internet and they can add government viruses that you can't remove and they can remotely control all of your devices and brick them if you try to send anything that the government doesn't like.
That's not even an exaggeration, once they enforce OS-level age verification via remote attestation they don't even have to pass a law to do this, they can send a secret order to Big Tech to do this.
I expect the government will require ISPs to only allow connection from approved operating systems that only allow installation of approved apps so we can't do this. Not in the short term, but eventually.
Probably by forcing VPNs to only allow approved operating systems to connect to the Internet via hardware attestation, then those operating systems will only allow users to install signed apps, and only government-approved VPNs will be allowed.
Zero knowledge proofs exist in theory, but none of these age verification laws that are introduced use them, probably on purpose. I'm certain that every government will want to know what sites everyone visits.
The people pushing for age verification have already said that they want to know who's behind every account on every website on the entire Internet. They won't accept any open or privacy-preserving standard.
Problem is a lot of apps require a locked-down device. You can't use a phone that isn't locked down in most of the world. And it will spread to PCs eventually.
The EU Digital Wallet requires hardware attestation so only it only works on locked-down government-approved OSes. That opens the door for government control of all electronic devices.
Zero knowledge proofs stops corporations from tracking you, but they don't stop the government from tracking which websites you visit.
They also require hardware attestation for them to work, which means you will be only allow to use a locked-down goverment-approved OS for age verification, and that opens the door for the government to control the software running on every device.
I doubt banks or the government would ever white list something like Lineage that's not made by some megacorporation. Also IIRC most phones don't allow you to relock the bootloader after flashing a custom ROM.
They won't need to do that. Once Google Play Integrity starts using remotely provisioned keys in a few years it will be impossible to hide root without exploiting a hardware or firmware vulnerability.
You don't own your PC either. All modern PCs have a Trusted Platform Module that the authorities can and will use to lock down PCs eventually. Multiplayer games are already using hardware attestation on PC for anti-cheat.
The Vietnamese government has mandated all banking apps to detect if either the phone has been rooted, the bootloader has been unlocked, or ADB is enabled and force quit if that's the case.
You already need to submit to iOS or stock Android for a myriad of banking or government apps that use remote attestation to verify that you are running "untampered" software.
If you live in the EU please complain about Google's developer registration (and other anti-competitive stuff such as Google Play Integrity) here. The EU is asking for people's feedback regarding the Digital Fairness Act.
