Well then, let's regulate this instead? Advertising companies already make a pretty good guess about a person's age. It doesn't require 3rd parties and age verification.

But we won't — this isn't why identity checks are getting lobbied.

I am confused. Are you saying that advertising companies should handle these identity checks? So let's just hand out a unique identifier to the companies who have monetary interest in this? Surely this will end well.
