Earlier quoted context omitted.
I still have a vague hope that the United States Postal Service could be "pivoted" into being a PKI provider and distribute physical tokens to citizens. They already have substantial procedures and infrastructure for verifying identity. There would be problems, to be sure, but I'd much rather get my ubiquitous PKI for citizens from the USPS than the banks or "tech giants".
It's a real shame the USPS didn't jump on email at the start and become an email provider
Though an official united states citizen email address has its own pitfalls for abuse, scams, and fraud.
