Purple thumbs are a pretty good system, and they were definitely not convinced by voting machines, nor paper ballots. But, it's a physical security nightmare. My job was to keep IEDs out of the polling places. There are many more issues such as multiple voting, cross-district voting, cross-border voting, voter intimidation, retaliation, etc. And imagine an academic suggesting that it's not practical. The most celebrated academic result of the last 25 years in the field was a crypto system that would take a thousand years to multiply one-bit numbers. Regardless, you're right. It is a waste of time. There's no funding. Academia is like consulting. You make money by telling people what they want to hear. I've become more aware of this.
