If you hack election software, you can change thousands or millions of votes as easily as one. The physical nature of paper means you have to work for each ballot.

Even for the paper side. Most paper ballets are counted by machine so they could easily be tampered with at the count or when they're printed having a similar scale.
Do you have a source for that statement? In Germany, ballots are counted by people making tally marks on paper.
Edit: Here you go. I couldn't find research or a study regarding it but this is probably good enough and was always my experience when I voted by paper: https://www.wired.com/2016/11/vote-counts-ballot-get-counted...
And recount-able by hand in case there is doubt.
One reason is that Americans vote a lot more than Swedes. Here in California I have probably ~100 elections to vote in for each I had in Sweden.
It's quite common to drop handfuls of paper. And really, the grouping comes down to transportation issues as well; when you move ballots in boxes and trucks, 0(n) becomes less accurate.
There were numerous issues with the security, packing, and handfuls of paper in 2000.

Not necessarily. I'm not cryptography expert, but I suspect some kind of proof-of-work system can be used for ballots.
