The public purpose of making this info available is to reduce voter fraud. I suspect this isn't obvious to most people. The reason that we can be somewhat confident that the dead don't vote too often or that non-voters don't vote too often is that it's not that hard for anyone to run a study of voters to find people who are actually dead or who deny that they voted.
