Thanks for your explanation. I understand what you're talking about, but this all just seems to be entirely orthogonal to age assurance mandates, which are largely about controlling which content and experiences minors engage with, in many cases regardless of what parents want.
Again, this isn't an endorsement of these mandates; I'm just saying that what you're proposing here doesn't address the objectives that policymakers who are in favor of these mandates are trying to achieve.
