Paper has two objective advantages over digital: It's reliable and it doesn't scale. That makes it the only option for elections as any compromise of a digital system would instantly decide the outcome. With paper, a bag of ballots might be lost or a few fake ones introduced, but none of these attacks scale very well so if we can prevent most of them, that's good enough. I won't touch on preferring paper for visualizing thoughts because that's just preference, but seeing people prefer paper invoices over digital ones is just sad to see. On a conceptual level digital should always be preferrable, but we somehow managed to screw the inplementation up so bad that it's worse than no implementation. Why do we need to overcomplicate everything?
