Drow "nation state is after me" from the threat model and you'll be a lot happier.
The history of tech is the history of falling costs with mass production. Expensive TLA surveillance tech for nation states can become broadly accessible, e.g. through-wall WiFi radar sensing sold to millions via IEEE 802.11bf WiFi 7 Sensing in NPU/AI PCs [1], or USB implant cables [2] with a few zeros lopped off the TLA price.
Instead of adversary motives, threat models can be based on adversary costs.
As adversary costs fall, threat models need to evolve.

- TLA agency deploys scarce zero days or field ops because you're particularly interesting, vs..
- TLA agency has everything about you in a dragnet, and low level cop in small town searches your data for a laugh because they know you, and leaks it back to your social circle or uses it for commercial advantage
Actually, once your e2e key that encrypts your data is out of your possession, it's out of your control.
Over the past decade it's become commercially feasible to be NSL-proof.
Once the data is out of your possession it's out of your control.
