Hold in your hand = physical access.

NAS counts

You can’t hold your NAS? It actually weighs very slightly more with data on it.

DVD have already polluted and currently exist and are rotting, and need to be ripped to longer term storage, especially for media that is becoming lost and needs a custodian to host so it can be pirated online. A lot of things cannot because no one has it, but it still exists in physical form.

Some may be ok with a whatever resolution streaming service webrip but I want the original dvd HD remaster, before they re-remastered it with only a single layer disk instead of double, messing up the original faithful rerelease that was already anticipated during filming when the show was filmed in HD widescreen film, but originally released in SD for broadcast due to the time. Plus, you can’t webrip the “banned” episodes if they’re not available.
