That's a huge stretch to say anyone that watches or listens to pirated entertainment would never pay for it. I wish people that use pirated entertainment would just admit that they don't want to pay for it.
It's the same stretch as saying people pirating content will never pay for it. All non-customers are simply not paying a creator for content. It doesn't fucking matter why they're a non-customer. From the perspective of a media publisher a pirate is no different than someone buying media second hand or never watching it in the first place.
If I buy a used Blu-ray I'm not giving a dime to Disney. I get to watch the Avengers all I want without ever paying them anything. They have lost nothing because I didn't take anything from them nor prevented them from selling a copy of the Avengers to someone else.
If you replaced my second hand copy of the Avengers with a pirated copy, nothing would change about the situation. Disney was deprived of nothing. The same is true if I rent it from the library, borrow it from a friend, or just never watch it. To Disney I am simply a non-customer.
