While I do agree that comics is a small enough market that people should buy them to read them I understand that sometimes people want to read more books than they can afford and therefore will buy what they can afford and "pirate" the rest. It's the same as sitting in the store and reading the book there. No matter how or where you read it you're reading it without buying it. At the same time "pirating" a comic is no different than buying it used on Ebay and it's no different than any other form of media that's not bought new, what tends to happen is that if someone likes the comic or other form of media they are more inclined to want to support the media by buying it new the next go around. This same topic is bought up in video games, albeit about used over piracy, and the answer applies to both cases.
