It depends on your purpose. If you’re an American who wants to make movies for Americans, that are derivative of one of these works, this matters a lot.
Plenty of people in e.g. India, Brazil, etc., buy literally counterfeit goods, dvds, blurays, and so on, all the time, let alone transformed works.
Often even with the exact packaging design of well known companies preserved on the counterfeit packaging.
And the purchases are often made via well known global payment processors.
Edit: At most a large fraction of potential US customers would be discouraged by the need to use a VPN for online streaming or by the risk of a physical disc getting seized. But that’s still far from zero potential customers.
