That's a powerpoint of somebody really trying to push an agenda and has nothing to do with age verification. The 88% support is for "social media platforms to protect minors from online harms, such as the promotion of eating disorders, suicide, substance abuse, and sexual exploitation."

I'm sure social media could say with 99% accuracy whether somebody is a minor already just based on advertising data and if a law prevented facebook from showing diet pill ads to a kid that has absolutely zero with some sort of government tracking bullshit.

The fact that you are citing 3 studies without even reading them apparently really makes me suspicious of your motivation here.
