Agreed this way is bad, but there can be a safe way of doing it. Basically, your digital ID has a way of signing that you are over 18 without giving any details. Estonia’s digital ID can do this. Imagine your digital ID has a way to sign documents with your age, but no other information. That way sites can know you’re over 18, without knowing your name, and the government doesn’t know what site you’re signing up to.
A less technical example of how this could work for the sake of explanation: You ask the government for a piece of paper that says you’re over 18. They don’t ask why you need it. All it has is a government stamp on it, saying you’re over 18. You give that piece of paper to someone trying to verify you’re over 18. They now know nothing about you other than that you’re over 18, and the government knows nothing about your activity other than that you want to prove your age for some reason.
Kids can still just use a VPN to get around this, but at least it doesn’t compromise the security of adults.
