Furthermore, as I said before, any business is subject to crimes, which are much more difficult to pull off than click fraud.
You seem to be assuming that most click fraud goes unrecognized. I doubt if that's the case. (Remember that Google, YPN, etc. don't have to recognize click fraud--they merely need to recognize what they choose to define as invalid clicks.)
However, not all businesses, even Internet businesses, are subject to click fraud. So the businesses that are subject to click fraud are more exposed to losses than those who aren't.
Sure, and businesses that are exposed to shoplifting or holdups are more exposed to losses than businesses that aren't. But that doesn't keep department stores, convenience stores, and liquor stores from staying in business, as long as the losses are a small percentage of total revenues.
