I’d buy a physical release of the series. I seldom buy discs these days because I’ve yet to be unable to stream anything I like. However, for the films I like enough to make full-film audio rips into MP3s for long drives or flights, I need a physical release.
There are lots of people who think Disney won’t ever release these because streaming subscriptions would go down. I could easily be wrong on this, but I doubt they would lose money. There are countless fans who have every release and box set of these films that have been offered through the years. There may also be plenty of people who either can’t or won’t buy all the streaming services offered but who may be more than happy to purchase a DVD set.
