That implies that you would prefer 3^^^3 people having pain at level 1 to one person having pain of level 1.00001, as long as 1 is not over the threshold for adding up but 1.00001 is.
As I stated before, doctors can’t agree on how to quantify pain, and I’m not going to attempt it either. This does not prevent us from comparing lesser and bigger pains, but there are no discrete “pain units” any more than there are utilons.
(Incidentally, for a real world version, replace “torture” with “driving somewhere and accidentally running someone over with your car” and “specks” with “3^^^3 incidences of not being able to do something because you refuse to drive”. Do you still prefer specks to torture?)
I would choose the certain risk of one traffic victim over 3^^^3 people unable to commute. But this example has a lot more ramifications than 3^^^3 specks. The lack of further consequences (and of aggregation capability) is what makes the specks preferable despite their magnitude. A more accurate comparison would be choosing between one traffic victim and 3^^^3 drivers annoyed by a paint scratch.

If you can compare bigger and smaller pains, and if bigger pains can add and smaller pains cannot, you run into this problem. Whether you call one pain 1 and another 1.00001 or whether you just say “pain” and “very slightly bigger pain” is irrelevant—the question only depends on being able to compare them, which you already said you can do. What you say implies that you would prefer 3^^^3 people with a certain pain to 1 person with a very slightly bigger pain. Is this really what you want?
