Piracy does effect the industry, not everyone that pirates "wouldnt have bought the game anyway" thats utter nonsense, while many would indeed never have bought the game to begin with, there are plenty of opportunists that were on the brink of buying and ended up just pirating it.
"its not an issue because they wouldnt have bought it anyway" is such a copout, someone not being willing to pay for something does not entitle them to take it anyway.
The whole approach to anti piracy does really need to be addressed and updated, but lets call a spade a spade here, when presented with the option of spending money or taking something for free with minimum risk, a large number of people will take it for free, that doesnt mean they wouldnt pay if that tempting "free" option wasnt on the table.
