If the website is tracking what you visit when logged in (which, they will be, as their business model is serving you relevant videos so you stay on the site longer to see more ads), and now the law is going to require them to verify that your account belongs to a person over the age of majority by storing your biometric information, then that is exactly what this law is doing.

Anyone who breaches that website's database (whether an inside job or not) is now going to learn not only what videos RandomUser782 has watched but also who they are, where they are, their birthdate, and what they look like; and if they chose to prove their identity via driving licence, also, their home address.

If this doesn't strike you as completely fucking nuts, I don't know what to say.
