“No method of online age verification is privacy-protective, fully accurate, and capable of guaranteeing universal coverage.”
Every age verification bill now waves zero-knowledge proofs around like a get-out-of-surveillance-free card.

The centralized system wrapped around the math is the problem, and no proof fixes that.
