The problem with that method of evaluation, is that it's not First Principles. Basically, pg's essay in this case just reduces down to, "Is that person steered by First Principles thinking?"
Most people ain't steered by first-principles thinking, though, and that's the problem. To most people, first-principles-driven thinking lacks sufficient actionability; they just want definite answers, and first-principles-driven thinking tends to produce answers that are anything but definite.

Often when I hear principled stances they’re entirely devoid of links between the real world and the utopia in the person’s head.
