This is true. But honestly even if most of media I watch is from “sharing” sources, without seeing nice covers on my Jellyfin instance and Kodi app I would not buy so many movies and music eather.
Not speaking for everyone, this is just how I am but once every a couple of months I order some movies even if already watched because I… like this. Having separated bought and downloaded media is nice and seeing bought directory is satisfying, even if media companies seems to not let me easly buy things nowadays…
