> There isn't even a concept of a method of doing this that would make that true, and certainly not in any of the implementations being considered in the US. The federal bill is called the Parents Decide Act, if it gives you some idea where the goal in decisionmaking is supposed to be.

The Parents Decide Act (PDA) goes considerably farther than superficially similar sounding laws like California's.

The California law requires that an OS allow the parent or guarding to associate an age or birthdate with the account when setting up a child's account on a device that will primarily be used for the child. It does not require any verification of the age information that the parent provides.

The PDA requires that the birthdate be provided for anyone who has an account on the device, and leaves much of the details up to the Federal Trade Commission to work out in the first 180 days after is passed. The wording of the list of things the Commission is to do suggests that the OS is supposed to actually verify age information, rather than just accept whatever a parent enters when setting up the child's device and account, and that it also has to verify that it will require the birthdate of the parent and verify that.
