> Digital files also require power to access and maintain, and are incredibly unstable over time as new operating systems, plugins and standards render things unviewable- often within a decade. They are also vulnerable to bitrot and physical degradation of storage media- the stable shelf life of a CD-ROM, for instance, is less than 20 years.
This is pretty much nonsense. The actual artwork on a piece of paper will typically be lower fidelity than a digital version of it, and paper degrades faster than CD-roms. I've dug out a CD full of photos that spent 10 years in a damp attic, and the photos are as good as the day they were taken - try that with photos printed on physical paper. Furthemore, while an NFT is by design not copyable in some sense, it's certainly not vulnerable to degradation of physical media.
