Just to play devil's advocate here, what would be the down side if no one studied political science? The country managed to survive pretty well before that field of study was even a thing.
Yes, including the field's worth and the counterfactual that it doesn't exist as a field of study.

But, like, sincerely, first they read some Plato/Aristotle/Machiavelli/etc, second learn about mercantilism's failures, third about modern coopetition in light of the multigenerational UN stalemates, fourth about the Laffer curve,

Sorry, I don't play with devil's advocates.
If this is your actual view, then just admit it, and don't pretend to hide behind an imaginary devil.
