Because physical media has effectively been contained and they can still make money from it. In the 00s, people mass ripping DVDs and sharing the contents was common. You could crack open limewire and search for any TV show or movie and someone made an mpeg or an avi of it. That culture is totally dead. Most normies will just stream now, and those who won't, won't be ripping the DVD contents and sharing them. All the places to do that easily have been obliterated. Do you really think the average normie is going to take the time to make torrents and find some sketchy tracker in Russia to upload/download Battlestar Galactica reruns when they can just summon them on whatever slop streaming service, on demand for like $10/month and have it be on their phone inside of an app, a half second of effort away?
The culture and technology of piracy has largely been smashed, so at this point, there is no risk on selling physical media. Especially given that such media is limited in how long it can actually exist by entropy. You could, probably at this point find DVDs from the 00s, which were well cared for, and still won't work because sitting still for some number of years was sufficient for the chemicals which made up the physical object to begin breaking down and deteriorating.
>tl;dr: Because physical media is culturally amd socially irrelevant.
