These discussions remind me so much of the US discussions about federal ID documents as verification.

There's a vocal portion of people which opposes any solution because "privacy, government overreach, surveillance ...". So instead of a solution like e.g. zero-proof age verification, that tries to minimize intrusions on privacy, the result is the worst of all worlds, maximum surveillance (but I guess it's ok if it is not the federal government, but meta), with minimum utility. Just look at the freaking mess that is trying to proof your identity in the US.

For there to be a solution, there needs to be a problem. These bills are not addressing a problem. Assume the online platform has a video feed of my kid, or their SSN, or a zero-knowledge-proof of age, or whatever.

Now, what will the platform do with it? Concretely? As in: Name one bad outcome a reasonable parent would care about that's prohibited under these bills. If the bad thing happens due to willful negligence, then there needs to be some actual material consequence to someone at the platform provider.
