Extant information is safer than just uploading an id (which is what the laws want). No one needs to know your birthdate or identity if your account is 18 years old. No one needs to know your birthdate or identity if you have a cc on file (you gotta be an adult to have a credit card and therefore to have credit card on file). This is the best possible solution, where there isn’t a requirement to upload a scan of a government issued id.
