Most important value of the 8 Values of Free Expression (in my opinion)

In my opinion the most important role of the government is the value to Check on  Governmental Power. Without this value, all the the other values wouldn't be possible. The liberty to allow citizens to check on the government without any retaliation from the government itself is what separates us from a dictatorship, communist regime or a monarchy. The Watchdog role that the media is provided is one of the most essential roles that they have as reporters, actors and writers. If news stations weren't allowed to report their opinions on the government than the government would get no feedback from the people that they are trying to govern (unless there's a riot/revolution). Just look at how upset Trump gets over the slander that he gets from the media on shows like SNL. Late Night shows genially make issues of the government the core segment on their show; by spreading the issues of government and the abuses of power on live television they're educating people that wouldn't usually look into government affairs to see what's going on in our society.
