Trypophobia is presumably an abnormal, overly-aggressive version of the disease-avoidance mechanism, though; there's no evolutionary reason to be unsettled by holes on inorganic objects, or even most kinds of holes on organic ones. Presumably, almost everyone has some level of the underlying mechanism; go look at a picture of a smallpox victim and see how you feel about it.
