This whole dust vs. torture "dilemma" depends on a couple assumptions: (1) That you can assign a cost to any event and that all such values lie within the same group (allowing multiples of one event to "add up" to another event) and (2) That the function that determines the cost of a certain number of a specific type of events does not have a hard upper limit (such as a logistic function). If either of these assumptions is wrong then the largeness of 3^^^3 or any other "large" number is totally irrelevant. One way to test (1) is to replace "torture" with "kill". If the answer is no then (1) is an invalidate assumption.
