The point is not using people in place of machines as trust anchors. The point is that you remove the trust anchor (or move it to the public at large, really).
In a properly run paper election, there is no individual that you have to trust. In principle, anyone can go and watch, and usually there are representatives of many/all parties in every polling place, watching every step of the process. It's not just that people are more difficult to coordinate or control in general, it's that if someone distrusts you, they can come and watch for themselves.
