The goal isn't to hide from the NSA, but to box out corporate surveillance and become sovereign within the civilian realm.
Folks running from government have an entirely different threat model that requires hardware isolation and, likely, no SIM/eSIM usage at all.
The NSA won't use their remote capabilities unless you become targeted. But unfortunately that likelihood goes up every day as the line between civilian and insurgent is a database entry. That targeting scales with AI. I know options are limited but the threat needs to be acknowledged and builders need to keep working on solutions.
