You can cryptographically sign things with your private key on your device also, which is put there when you register to vote. Either way, someone can theoretically forge your signature. You don’t have to get a list of those who didn’t vote. You just take the pile of punched ballots or whatever and replace them with your pile. All the matching of counts etc. can be done electronically too.
Unless your device is compromised.

They could forge your signature, but to be effective, they need to forge thousands of signatures.

No, the ballots all have unique numbers and the list of numbers is stored separately. You'd have to buy off all the poll workers to pull that off, and you'd have to reconstruct all the records to match your fake ballots.

Sure it can be, but not securely, and security (and integrity) is the number one goal of a voting system. Convenience and speed are secondary.
Let's put it this way -- the State of California only does paper ballots. No voting machines are allowed in the most populous state. Why? Because they engaged many security consultants and couldn't figure out a way to vote electronically that was safer than paper.
It takes over a month to certify a California election, because every ballot is cross checked with the precinct records, they randomly recount various boxes of ballots, they check that the outcomes are in line with the polling data, and they verify every single signature on every absentee envelope.
