Why?
We don't externalize age verification when buying alcohol or visiting the strip club. It's on the responsibility of those establishments to verify age.
It works for the in-person context because it's a physical object, making it easier to control access to it. A high resolution picture of the same ID is a privacy problem as it can be copied, shared, transferred, etc without the knowledge of the ID holder.
I think that main goal would be to keep the ability to have accounts be anonymous or pseudo anonymous.
If social mean company has to verify an accounts age themselves they then have to use some for of official government identification and with that any chance of anonymous or pseudo anonymous access.
My comment was not about what I knew/know about facebook or not. I was answering the question of why age verification should be externalized to a degree and in this case externalized means the power stays with the user and parents rather than being in the hands of say facebook/meta.
I was not talking about why facebook/meta would want it or not want it. Large companies want lots of different things. Sometimes it is required to know their motivations to discuss or decide on something. I think it can be detrimental to do that though without discussing/analyzing a topic/idea on its own merits first or at least parallel. My comment was focused on the merits not the motivations or desires of companies like facebook.
Meta Apps can have age verification but it should be at the point of service, not the supply chain.
And even if we were to agree to this, uploading your IDs to an untrusted third party is asking too much.
So have the government do it? They already know who we are and when we were born.
But in a perfect world it would be parents doing their job and parenting. You can grab your child's pad, phone, laptop, whatever, and black list the entire internet allowing only a few select white lists of your choice. But it's too hard to educate parents on how to do that I guess, assuming this was ever about children and not data collection, which it is that.
