You raise a very good point.
Obviously, we need to find alternative means of voting during this pandemic or maybe a future national emergency. In those circumstances, I think the best worst alternative is proxy voting. It's not something I encourage, but I do believe that, in these circumstances, it's better than virtual voting, electronic voting and remote voting.
I wouldn't want this to become a precedent that then allows it to carry on beyond a national emergency like this, but I do think during an emergency it may be the best worst option, if I can put it that way.
