The real reason to keep physical versions of content is if for some reason Apple decides to take down the show it is gone. You cannot access it anymore through normal consumer methods.

It’s actually a problem you can see in other genres and if you don’t believe me you can google it yourself. There is totally a reason to buy this stuff if it holds that much value to you. The service could be $.25 a month and you might want to own the show in another format. That’s completely fine.

That being said if you have content that you arbitrarily refuse to sell to someone that wants to hand you money, I’m less concerned with the alternative means someone might take to get it.
