We're already not free to walk around without papers for certain activities. Entering a bar, buying restricted substances (including some medication!), driving a car, leaving and entering the country, etc. None of that means we're in some totalitarian dictatorship. I've seen plenty of elections come down to 100s of votes. To me this seems like an attack vector we shouldn't ignore. Besides, we already have the concept of provisional ballots if people end up not having or forgetting their ID. But again, I don't think we're ready for all this. A half-assed solution would be very bad, and I don't trust the current system to handle this in a partisan way.
