Media and software are not examples of post-scarcity economy. They require hardware, which requires infrastructure, which runs on the expenditure of fuel and calories, and is built oftentimes with slave labor. The music needs to be composed, the movies need to be filmed, the games need to be designed. Storage media needs to be replaced. Programmers need to be educated generation after generation, and then everything rewritten in new languages when no one cares about the old ones. Factories need to keep building new models and old models keep filling landfills. The digital world is very much tied to scarcity of resources. Every bit flipped contributes to the inevitable heat death of the universe.
