I’m not disputing the validity of the thought process. I don’t think the example was well chosen, however. A dust speck, ignoring externalities, doesn’t affect anything. Using even a pinprick would have made the example far better.
It’s an extremely hypothetical situation. However, why should it, ignoring externalities as the problem required, be measured at any disutility? That dust speck has no impact on my life in any way, other than making me blink. No pain is involved.
I would simply argue that a dust speck has 0 disutility.
Pick some other inconvenience which has a small but non-zero disutility and repeat the exercise.

That’d be Fighting the Hypothetical.

Because it’s one of the parameters of the thought experiment that a dust speck causes a miniscule amount of disutility.
