I’ve never known a group bang about rights the way pilots do.
You have the right to use GPS. Really, you do. Happy now?
The US government has the right to switch it off, and the MoD have the right to jam it. Where does that put your right? You don’t have the right to stop them, and you probably don’t have the right to action against them nor compensation from them if that happens.
You also have the right to exercise airmanship, which might include identifying single point failures that might impose hazards on the flight.
Staying alive, on the other hand, is not a right but a privilege.
