Here in the US from the earliest pioneering days of radio technology we've had a widely accepted understanding that its legal for anyone to receive any radio broadcasted signals. This is the prime/bottom layer, then we start adding layers of complexity on top of this (encryption, licensure, public safety, etc). So if you're generating radio broadcasts (via the seemingly dormant cell phone in your pocket), you have no right to assert "privacy" to these transmissions. If you want a state of things that most closely resembles "privacy", you have this option: you can either shut down your radio shack entirely (shut off your cell phone), or leave the radio shack on and simply kill the power line going to your transmission antenna (put your cellphone into "airplane mode"). If "privacy" is so important to you - then just stop broadcasting radio signals... don't argue to change our ~100 year laws guaranteeing the public the right to freely receive all radio broadcast transmissions.
