Uh, recheck that. The park in front of my place is constantly busy with ppl playing sports in large groups, the gym in my building is packed at all hours, and personally I start every day running before showering. Don’t think I’ve missed more than three or four days this year (and that was due to travel/flights). Routine/habits are powerful motivators, both in positive and negative directions. And fast food I dislike (and it’s more expensive than comparable local options in my country like bar food or street food) so I don’t think I’ve had fast food from a chain or similar since the pandemic.

This seems to be a gross misunderstanding of public key cryptography. Public keys allow you to verify an existing signature is valid and made by the correct entity, but they absolutely don’t allow you to forge a signature: that’s actually what they are designed to prevent.

You pay CAs for certificate issuance, not for signing. You could sign all the QR codes in a city with a single CA-issued certificate as long as the standards for it were all accepted.
