Your first two statements are a straw man and thus, become a non-sequitur.
> As soon as you declare the possible effect to be effectively infinite in magnitude, you can justify any level of response to any level of risk.
The possible effect is not effectively infinite in magnitude, and no, it does not justify any level of response. Even if a rogue state decided to bomb a plane, that would not justify a nuclear strike in response.
The common sense that you urge is already being applied, and based on well established, well tested protocol. It's not authoritarian to tell someone to turn off their bluetooth on an aeroplane because they named it in an offensive way. That's common sense.
You can't just make a strawman and then when someone calls you out on it claim that they're making a strawman.
Though I'll admit, you gave me a good laugh. But troll harder. Either try harder to sound like an intellectual or learn more into the crazy fingers in your ears "la la la" character
