Think about paper ballots:  The system has to insure that no one but you can see what you wrote on your ballot, but also that your vote is actually counted correctly.  To count votes, someone has to see the ballots!  So what we do is make sure that no one can tie a particular person to a particular ballot - and that no one can remove ballots from, or adds ballots to, the ballot collection box.

That is an excellent point - and more to the point than the one I
made.  The requirements *are* different, in authentication and
privacy and in which endpoints are trusted.
