The reason to switch from resold to infringed is that infringed is a superior substitute. However, these are not the only two substitutes in the market, and given that the consumer is consuming a stream of items over time, it is the case that by switching to infringed that the consumer will have less reason to ever buy, either at all or in the same quantity, the substitutes that make money for the creators, such as paid streaming or new discs, and so it is plausible (and for many individual consumers likely) that the impact on creators will be non-negligible.
