> There are outlier problems preventing this from being perfect
These are not outlier problems. I have been election official in Finland and it's not rare to see husband trying to make his wife to show the ballot. Smartphones are already creating problems that are hard to quantify.
The real solution comes from doing basic things right. Electoral observation can be improved. Paper ballots standard where ballots can be quickly counted using electronica counters from multiple suppliers (different parties can bring their own) can make voting both secure and safe.
