Yeah I know what you're saying, but as people have argued, the stats on piracy are far more complex than the game industry makes out. A pirated copy does not mean one less sale, etc.
My personal example. I bought an Amiga because I knew other people who had one and I knew I'd be able to copy their games. I could have bought a Megadrive at the time but didn't as this was a strong argument against that. Console games cost a lot then.
Yeah I had loads of copied games, but I also ended up buying quite a few. You can argue those purchases came purely because of piracy.
