Understandable, but then vote-buying becomes possible. The reason vote-buying is impossible in a secret ballot is because you can't prove how you voted to anyone else. If you can look up your own ballot even five minutes after it's dropped into the box, then you can show your screen to someone else who then hands you $100 for voting the right way, and elections change from being "who has persuaded the most voters?" into "who has the most money to buy votes with?"
Or despot, or ruthless water district rep (lol)
That "if" is doing an awful lot of work here!
You can literally explain paper voting to children - it was part of my mandatory Civics classes. On the other hand, I'm pretty sure you need a cryptography PhD to even begin understanding why the various digital protocols are supposed to be secure. Even worse, as a software developer I am aware that things like "how do I know the compiler is trustworthy" and "how do I know the computer is in fact running the right binary" are very much open problems in the industry, so I know that any computer is untrustworthy.
Sure, if it's transparent and verifiable there's no reason to distrust it, but we don't live in a world where a transparent and verifiable digital voting system has been invented yet, so there are plenty of reasons not to trust them.
