I don't want the market solving this. If we are going to do age checks it should be based on public key cryptography, be open source, and handled by the government. You verify with the government (or don't since they already know your age), you get some form of cryptographic attestation, present said attestation to websites/apps.
I'm not a fan of age verification in the first place, but I am extremely not a fan of random third parties doing the verifying.
