Is Sancho Panza fit to govern?

So Sancho Panza has finally had enough - when some of his "subjects" barge into his room at night, convince him that the castle is under attack and that he has to be their fearless leader - they strap him, naked, inside two shields and tie him tight so that he can't move - he topples over, they trod all over him, battering him once again, then they cheer and thank him for leading them to victory. They take him back to bed and he basically passes out - at which they feel a slight bit of remorse. These are the subjects of the duke and duchess (never named) who are getting such pleasure out of tormenting SP (and Don Quixote as well). Then, to their surprise, when Sancho awakes he says he's had enough of this, he was never meant to be the governor of an "insula" and he had no idea how stressful the work would be - he'd rather govern his herd of sheep or goats, and so long as his faithful (never named) gray donkey has enough grain he's happy, and he saddles up and leaves - to their mild amusement. Is Sancho really unfit to govern? Obviously not - he's shown himself to be more wise and thoughtful, let alone more compassionate, than those in power. To paraphrase the great contemporary writer William Trevor - from the conclusion of one of his stories: The failure was the world's, not his.
