Arbitrary power can achieve a lot of good things but it always ends the same way. So better WiFi on the plane but one day you find you can't get on a plane anymore because you said the wrong thing.
But also "I am going to Colombia to bring some cocaine home." and "I am going to Washington to assassinate the president." and "The right of the people to keep and bear nuclear bombs shall not be infringed." and any number of other things that don't immediately threaten the plane's integrity.
