1. This California law doesn't require IDs. (Some states like TX do, but mainly for websites "harmful to minors"). 2. If I have to think through your examples -- purchasing cars and arms requires strict ID checks that go further than age verification. If a kid drove or use weapons owned by their parents, I'm mostly confident parents are liable in most jurisdictions. But I think I can guess out your concern -- 24x7 online tracking can be much more intrusive and terrifying than a one-time background check -- which I actually agree. 3. In fact, you can think this law exactly require OSes (thinking of as iOS/Android/Windows/macOS) to "give the tools to parents" -- being able to indicate that the user is a minor at OS level and expose that information to apps.
