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.
Because we’re currently still in the phase where lawmakers are telling tech companies “please find a solution for this issue.” At some point, as has happened in the past with other issues, this will change to “solve this issue, here’s exactly how you have to do it.”
