Your example is in bad faith as your example assumes that the only thing blocking a child of 5 from porn is age verification of some type. There are lots of blockers today for 5 year olds to get access to porn.

Nobody on the "we need age verification" side wants a debate. They want to run face first in to dumb legislation giving governments and companies even more power to track every movement and know exactly who you are.
The blockers generally don’t work (I’ve tried). A big part of the problem is that it is in the interest of the providers to subvert them. The main benefit of age verification is changing that responsibility by making it the business of providers to ensure it works, not consumers.
You can make the same argument with alcohol: surely it’s sufficient that parents supervise their children not to drink. But it’s prove to be more effective to distribute that responsibility to the providers as well.
