in the words of every hacker ever: "What's your threat model?"

nation state attackers are fairly infallible, unless you're personally gifted and/or well resourced...

check out Clearview AI - and remember this is a commercial, non-classified effort!
E.g.: https://www.nytimes.com/2020/01/18/technology/clearview-privacy-facial-recognition.html , https://www.cbc.ca/news/technology/clearview-app-privacy-1.5447420

finding the friendly landlord landlady who likes cash, month to month, is great. not that digital payments are not cash equivalents, however!

check out "The Find", and other techniques that are designed to work against burner phones; they attack pattern of life data exhaust across all cell tower radios in addition to targeted attacks against specific baseband chipsets of "selected" targets....

next up, employ a mixer / tumbler when transacting BTC to avoid deanonymization attacks against the network itself. :P
E.g. https://github.com/JoinMarket-Org/joinmarket-clientserver , etc...

note that tower based triangulation is nearly as effective as GPS, in terms of geolocation privacy risk.

indeed! as mentioned before:

first deploy encryption to kill passive Eve's ears.
then keying Hardened end-to-end to avoid active Mallory in the Middle.
finally, harden Physical Security against burglary and rubber brutes...

side benefit of privacy enhancing technologies like Fully Homomorphic Encryption: they're resistant to quantum attacks (e,g. Post-Quantum ready crypto :)

C.f.: https://github.com/homenc/HElib , https://github.com/IBM/fhe-toolkit-macos , etc.
