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.

Please explain how opposition to privacy invasive solutions result in even more privacy invasive solutions being implemented? Is it purely out of spite from the lawmakers? This logic doesn't follow.
It’s obviously worse for your privacy to have third parties handle full images of your drivers license or video of your entire face, which can then be leaked, rather than using a zero knowledge proof that only sends e.g. a birth year. And no, it’s not spite, it’s incoherence. Lawmakers are single minded seekers of re-election to a first degree approximation and will do things to get votes, even if those things don’t logically make sense together, such as requiring age verification without providing the tools for companies to abide by the law themselves.
US lawmakers are single-minded seekers of lobbying and insider trading money, they will sign and trade on whatever ALEC hands them so they receive more money.
