Counterfeit what? This is about labeling and filtering: the device doesn't present an ID, the device prevents the user from accessing content with/without specific labels if so configured.
Specifically, governments mandate that:
1. Websites/apps/etc. MAY label content (via headers) indicating when their content/service is/isn't appropriate for some specific audience (e.g., children) according to X/Y/Z regulations. Websites/apps/etc. MUST NOT incorrectly label their content.
2. Devices that can access the internet must not be sold directly to miners without parental consent.
3. Devices that can access the internet must include parental control software can be configured to allow/forbid all apps/content that may contain content not deemed suitable for children (in the jurisdiction where the device is sold).
Importantly, this kind of solution solves the "borderless internet" problem:
1. Device sellers are regulated in the jurisdiction where they sell the device.
2. Service providers take no (additional) per-jusrisdiction responsibility until they start labeling their content. By labeling their content, they are claiming to abide by specific regulations.
