Courage is a non-technical term which I hate. I think he means disagreeableness based on his wording which I’d agree that excessive agreeableness is probably more detrimental than excessive disagreeableness, but it seems like maximal disagreeableness would also be bad.
Courage is an emotion. Emotions matter. Don’t try to eliminate them for the equation just because you don’t like them.
