Prophet of the profane (She/Her)
And there are procedures to check both for doing their job badly.Look, if you want to appeal to human fallibility, sure.
"Even though judges are supposed to be impartial, they can just say you're in contempt and put you in jail, so why bother with judges, amirite?"
"Even though the referee in the basketball game is supposed to be impartial, they can totes just call one side for fouls and not the other, so why bother with referees, amirite?"
Other than that, the laws and rules that they operate on are well known. The spectators at a basketball match can see the fouls with their own very eyes, and even if some reason the referee wouldn't face any repercussions, everyone will know that this match was naughty word. A lawyer can see that a trial was naughty word the same way.
In D&D, who knows how the dungeon is supposed to look like? Who know where the traps are and how they work? Only one person. The GM.
This doesn't mean that poking at things with a 3m pole (let's name things properly, not like americans) can't be fun. I just doubt that it can actually be a real, genuine test of players' skills.
