I interpreted this as meaning "it's obvious that it's wrong but since it's hard to directly connect with the victim the threshold for doing it is very low". I agree that it did come across a bit ambiguous as to his actual meaning. The perennial Simpsons quote "Shoplifting is a victimless crime...like punching someone in the dark" would've been a more direct illustration, at least if the author meant what I think he meant :)
