We've done both. My question is, what paper backup. If you vote on a paper ballot your name is not on it.
If you get a receipt for your vote...so what. Most people would not keep their receipt. The truth is the voting process will always involve faith. Unless your vote is recorded on paper with your name attached to it in some way, there's no such thing as an actual paper trail. And to have an actual paper trail violates you privacy of the vote.
If you think about it, most of modern life is a leap of faith. We are conditioned to expect that our vote is recorded correctly, that our taxes are correct and mostly fair, that paper money has an actual value, that the beef we buy in a package is actually beef.
Most of our existence is based on our conditioning to expect certain responses to certain actions.
Ok, sorry...I'm just having a moment here. But still
