In your system, can companies verify age offline, or do they need to send a token to the Government's authority to verify it (letting the Government identify and track users)?
Switzerland is working on a system that does the former, but if Government really wants to identify users, they can still ask the company to provide the age verification tokens they collected, since the Government hosts a centralized database that associates people with their issued tokens.
