It does not make sense to paint paper ballots as something that is inherently better.. Paper ballots have many potential vector attacks many of which are stupidly easy or even unintentional (e.g. hanging chads)
Hanging chads, which are anyway still a problem introduced by machine-counting, not hand counting, are much less problematic than hacking a voting machine. There is no tie between your vote choice and the probability of a hanging chad, so this doesn't bias the election against any particular candidate. A hacked voting machine does have intentional bias.
Hanging chads were caused by a dumb idea to make ballots automatically countable. The solution is to make ballots easier to hand-count, by having separate ballot papers for each position (or at least the most important ones) and counting them by hand.
