Scaling an attack against paper is incredibly difficult, and requires coordination in a level that is almost sure to trigger the law enforcement much before it can change some national-level numbers.

Scaling an attack against a computer system is almost the same as doing an attack against a computer system. Few attacks don't scale.

But yeah, if you just print the vote and push it into an urn (while the voter can read it), you'll get the best of both worlds.
