That wasn’t true for iTunes where copying MP3s was trivial. Of course theirs still piracy, but why did the DRM-free Witcher 3 make millions of dollars? Your argument just doesn’t hold up with real life data.
Music was completely different. The RIAA was suing pirates for thousands of dollars, and Apple provided both a store and great hardware for their product. People cheered them on for finally convincing the music industry to make content digitally available. It turns out all people wanted was easy access. And now for things that could be desktop software, we have subscriptions, memberships, etc.
