I only made my comment because they were already in the used market and I don't think most people who buy movies do so with an eye towards the resale value, so there is minimal impact on the creators' pockets at all.

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.

I’m not sure that follows. Someone bought the content new. When someone else buys their old stuff, this gives them more money with which to buy new content. I suspect this is a very small effect, but I doubt it’s zero.

As I said, minimal. If I save money by pirating content and then use that money to pay higher tips to service workers, then maybe they'll turn around and buy more content - helping content creators. These are very tenuous links.

The more clear link would be the used market shifting the demand curve for the new market outwards due to the resale value. I think this is a real effect, but a small one.
