I do crypto the airport (opening the barriers with my passport, where the computer in my passport signs a challenge encrypted with its pubkey) and do crypto with my phone (making a call, which is encrypted with Ericsson SNOW), and do crypto at the corner shop (using my card, same as the passport).

If airports, phones, and corner shops claimed they 'work in crypto' it would be similarly misleading.

FWIW I work in web3/defi, used to work in PKI.
