So these attempts by governments to introduce online age verification requirements, are these going to use zero knowledge proofs?

Are they trying to sell this by floating the idea that you can prove your age while still remaining "anonymous" in some sense or another?

From what I'm reading, it seems that zk proofs won't really work to achieve this in any truly meaningful way. See for example this for a critique:

Does anybody have any insights into what's going on here?
