I ask because there was a similar moral outrage around age verification for access to porn sites that I recall being a big issue a while ago. I don't recall exactly how it played out in court, but it appeared to amount to nothing, which I can't help but to feel was due to the fact that mechanisms to verify someone's age online are either trivial to circumvent or present such a high barrier to entry that no reasonable user would surmount it.
But in all seriousness, age verification will soon be a legal reality. It's only "hard" because it's optional. When the government makes it required, they'll also have to make it possible - or those laws won't stand up in court. It'll probably require government issued digital IDs and MFA hardware.
No anonymity on social media sites. Not saying that's desirable - but it's the logical conclusion. You can run your own site anonymously.
> how do you do this in a framework that works globally
Lots of things work globally but are subject to local laws.
Mandated ID checks are fine as long as we're using it to bludgeon the privileged in the process?
