The reason that we dont live in caves is because we evolved. That’s the same for all technologies. How much payload do you need to cause havoc - its all about the potential to do it and stopping it before it ever happened? A navaid will get you to a point, a known point which is pre defined. A GPS unit will get you to ANY point that someone wants.

Don’t underestimate model aeroplanes, they can come in a range of sizes. Have a look at LMA on Google if your not sure.
I quote below from one UAV autopilots website, surely its easy to see the potential threat from such a unit and the reason that a jamming unit is needed. Its got to be better than switching off all the signals...
