This falls apart immediately: what about household computers? *Plenty* of families don't even set up unique user accounts for each individual user of their computer, so how is that expected to be handled when they have a mix of age ranges on the device?
And if all the "verification" is is entering a birth date upon account creation, this will be super easy to work around, but it's entirely likely this whole thing is simply an attempt to chip away at one end of the Overton window on this topic anyway and much much worse legislation is already planned.
