Economically in fact, piracy is a good thing just like any form of spoilage. Imagine if you bought 10,000 apples and they never, ever, spoiled? You'd still be eating those apples when you were 80 years old. You'd never have bought another apple in your life. You'd have expensive storage costs over 80 years.
Are you seriously trying to argue that it's a good thing apples go rotten? And that's why piracy is good?
