Not the other guy but piracy isn’t an automatic loss of sale. I’ve bought plenty of things I originally wouldn’t have, because piracy was my “skimming the book” before buying. Not being able to pirate is like seeing the plastic wrapped book and going “I’ll just look for something else then, I don’t want to waste my money on something I’m not sure I’ll like”.
If someone has decided to pirate something, they had already decided it wasn’t worth buying to begin with, they were already a “lost” sale.
