Thank you for the insult. The point is that commuters generally have a much longer trip to their starting point than non-commuters. Obviously edge cases exist, but the exceptions prove the rule.

We argue on one hand that deadheads and sits are fatiguing to the point of danger, but defend them as restful when it serves us with commuting. We argue that circadian rhythm flips are fatiguing and dangerous, but ache for fully commutable trips. Pilots are not now, nor have ever been, actually interested in fatigue science in an objective way.
