Let us accept that sending a text message about wildfire danger is legitimate. (I'm sure there are some here who will argue that it is not, but let's ignore them for the moment.)

Sending a text message "to honest and loyal men about confronting the traitors and criminals and protecting the people and honor of the country" could be legitimate use of the threat of violence to defend the country. Or it could be a horribly illegitimate abuse of power, in a much more fundamental way than a wildfire warning could ever be.

So that's what bugs me about your examples. The second one is far too open to illegitimate use. And if the use is illegitimate, then the monopoly on violence is not legitimate either. (At least not within US civic philosophy: "Deriving their just powers from the consent of the governed", and all that.)
