Fraud doesn't just cause merchants lost goods. It makes ordering from stores more difficult when there are extra steps (at least 3-D secure) just for fraud reduction. This both annoys customers and causes sales to be lost because ordering is less convenient. It causes unnecessary returns when merchants end up sending things to non-existent addresses that someone just invented to see if their stolen card was working or not. It even makes things like A/B testing less reliable, when your numbers are skewed by fraud. Eliminating an extra step in your order process might look like a great A/B testing win. Unless it was just because that "optimization" just made fraud easier to commit. At the very least it adds noise. It also makes it more difficult to know where you as a merchant stand financially, as orders can become reversed in the future. Even if you seemingly turned a $1000 profit this month, later you might find out you actually didn't. It's a sad situation that we have to just try to guess who might be committing fraud or not, sometimes denying service to perfectly legitimate users while still missing many cases of actual fraud.
