An analog print is a unique thing. Even if one has highly disciplined darkroom technique, no two prints will ever be truly identical. EVERY digital print is metaphysically identical. That's a huge thing.
It's also not true unless your printer is magic! I'll give you "every copy of a digital file is metaphysically identical", but getting it onto a physical substrate is a physical process with the variability thereunto appertaining.
