PGP is an encryption technique, it doesn’t include any robust and tamper proof timestamping mechanism. To uphold the veracity of a time stamp and to make a PGP message censorship resistant you need either a trusted authority to continue to host and certify it, or a distributed network of validator nodes like Tor (10 validator nodes) or Ethereum (thousands of validator nodes).

If you remove crypto from this equation you are left with a permissioned solution. Which is fine for many uses, but not the same thing.

A practical example would be removing crypto from a USDC or DAI transfer between two people across the globe who wish to send USD-like asset, despite neither of them having access to a US bank account. The proposed solutions are to send cash in the mail, or PayPal, or whatever, and none are the same as a USDC or DAI transfer.
