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.

> I also acknowledge that there is a reasonable debate to be had if the disadvantages to adults and businesses from imposing these rules are worth the harms prevented

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.
