It's not about the age, but whole identity. You know you are serving ads to a real person and not a bot and so on and you can correlate person across different services with 100% accuracy. Currently you can still reasonably easy fake a persona.
If this is the case, this can be gamed. People can use stolen documents. Nothing says a person can’t own multiple computers so what happens if someone uses your id in 20 laptops? Will the companies just claim “but the machine said they where old enough?” The law may not have teeth, but will violate privacy.
Something like https://protocol.humanidentity.io (disclaimer: I built it, sorry for the plug) or any other privacy preserving service might work better. A platform can then require that a person verifies age in a privacy preserving way before viewing adult content.
