At this point, you might be right this is a better solution, but it is hackable. Add or remove paper ballots, mark existing ballots with your own pen to change or invalidate it. But at least the physicality of it creates some limit on the scale of fraud.
The recent Canada federal election used paper ballots (all of them have), and those attacks are mostly preventable. Ballots are counted by two people from Elections Canada, and all candidates can watch. The match up the number of ballots with the number of people crossed off on the list of people who were eligible to vote at that polling station. They also compare it to the number of ballots at the start of polling and end of polling. If votes were added or removed, those checks wouldn't work out (and there would probably be a re-vote for people who voted at that polling station). Adding marks before people vote wouldn't work since voters would probably notice, and it'd be hard to add marks between marking the ballot and it being put in the ballot box. Ballots also need to be signed by the chief returning officer.
