A similar system was attempted in the UK. The controversial part here was that there would be some central body with potential knowledge of the sites you visit associated with your passport/credit card/ official license. In addition the potential for fraud in spoofing the verification process etc... There was much humorous satire e.g. calling the Queen for access to porn. Before some tech contracts fell through and the whole system was abandoned at the end of the Theresa May government. I was looking forward to the tertiary effect of kids becoming network experts in the next 20 years.
