If you were responding to my post, then perhaps you've misunderstood what I meant.
If, as Persson puts it, a "potential customer" chooses to pirate a game instead, how is it not a "lost sale"? As you say, somebody might choose to pirate it initially, and buy it later. But the possibility exists that they won't. You can't have potential customers without lost sales. The concepts are mutually dependent.
