jzcbnmso Most answers to such "uncomfortable" questions look like you are defending this system and also fully trusting it, which fundamentally cannot be correct.
Using words like "fundamentally" or "uncomfortable" with no basis does not help your request, it shows that you lack the knowledge and also too stubborn to look into suggestions and explanations offered. Do you drive a car? Ride public transit? Use elevators? Airplanes? Each of those could end your life but you still use them - do you "fully trust" them? but, as you said, that jzcbnmso: "fundamentally cannot be correct", but yet you still use them.
What you're doing is trolling after being pointed out that your wish is unreasonable and lacks understanding in the system.
My recommendation to you: disassemble your phone, locate the BT chip, and remove it - FULL CONTROL
