> There is no such thing as privacy protecting or anonymous age verification

There most definitely is privacy-protecting age verification. You go to a government office, you show your ID, they give you a piece of paper that officially says "over 18 years old". Now you have a piece of paper that says you're over 18 but doesn't say who you are, and the government won't know where you use it.

On the Internet, the idea is the same, but with cryptography.
