I believe it is important to keep the physical version at a safe place for as long as possible. How long before a new wave of "flat earthers" decides the digital version is just a deep fake and it never existed?
Though I say for really important works, having a physical copy in addition to the digital one is a must. Digital data is easy to copy — and easy to lose. And bit rot is a thing.
What other discoveries might be unpredictable right now? For example, some new development might tell us two things were made in the same place and time, leading to discovery by inference, or something.
Originals might prove valuable in ways not yet known.
I don't believe anyone has ever convinced a flatearther with reason.
