Have you actually spent time considering whether age verification is beneficial?

Yes, and it’s not.

Whether parents think that their children spend too much time online, or whether the teenagers think that themselves?

That has no bearing on whether or not every single website, advertising service , and application needs access to my PII.

Have you taken their input and concerns serious?

Yes, but if they aren’t willing to take responsibility for themselves or their children, then I don’t really give those concerns much weight.
