Perhaps you can look into best ways to defend against biometric surveillance and maintaining sovereignty during long distance travel.

- Air vs Land vs Sea
- Fake IDs (might become as common as burner emails)
- How do Chinese subvert their biometric surveillance state?

Anyway, be good to hear thoughts on this subject as we will undoubtedly have to combat it soon.

I know the basic idea is "opt-out" but that advice is about as useful as suggesting people do not use email, phone numbers, or the US Dollar. Possible? Sure. But there are plenty of ways to subvert a system and not simply abstain.
