Ideological is the best way to describe the reaction by most people on here I think, counterproductive is another one. The reality is most normal people want children protected, unless we can come to the table with good options we are going to end up with a terrible one thrust upon us.
Slippery slope arguments and things like it are not going to convince people, "just parent your kids" is not going to convince people. Not because they're wrong, but because on balance they feel like the damage to children being exposed to this content is worse than the potential civil liberty issues.
It will be very difficult to explain to people why this is not the same as alcohol being age-gated and you having to prove your identity to access it. Technically there should be no real reason we cannot do age attestation without fully revealing our identities anyway, there will need to be trust at some point in the system but the reality of the real world is that there is already and it's far less secure than we'd like.
> there will need to be trust at some point in the system
This is why you don't have a technologically effective solution, here. "Trust" in this situation is a weasel word for surveillance, just like the pinkie promise that Client Side Scanning would never be abused by the government. Trust would not stop child abuse, or meaningfully prevent access to online pornography. Trust is not a technical solution, it's a political goal.
If you have a productive suggestion, now is the time to voice it. All of the non-technical hand wringing is not helpful either, and feeds into the slippery slope logic that HN should be avoiding.
