This seems hyperbolic as it's actually a long path between age verification to full digital identity tracking. But I agree that pushing the burden of verification to websites is ridiculous. Like the GDPR requirements where every webpage has an annoying consent modal, the verification and preferences should be controlled on the device you use to access these digital services. My browser should know and enforce my cookie preferences in a way that has a uniform user experience. Likewise, if I am a minor, my parent should provide me with a device (or profile on a device) which knows my age and can use that to inform online services of the age of the user rather than needing to go through a separate process for each service.
