"But age verification requires identity verification. Identity verification requires digital IDs." Um, no? iOS is doing age verification just by your credit card. I never saw people all that upset about giving their credit card info to their phone wallet app or even to a bunch of websites.
Are you going to give your cc number to every website in the world? Also, is that really an ID?
I would say it's not really an ID no, which is the point. The post is claiming that a digital ID is necessary for age verification, but clearly it isn't.
