Paper voting makes this better though. A key feature of the system is that the count is done by representatives of each candidate all counting the paper ballots together and not letting each other cheat. They also all man the voting booths throughout the day verifying that none of them is stuffing the boxes with votes. Anyone can understand and trust this system, whereas a cryptographic construct that <0.01% of the population truly understands is rife for rumors. Voter suppression and other ways to make less people vote are the same in both kinds of voting.
