The problem with individually verifiable votes is that of vote buying. Consider two scenarios, one where votes can be individually verified, and one where they cannot. A) Person stands outside of polling station in swing state/district, offers $5 for a verified vote. Walk in, get your receipt/blockchain entry/doodad, show it to the vote buyer outside, get $5.

Walk in, vote for whoever you want, then walk out and pocket the $5. Because the vote cannot be verified, they have no proof one way or the other. Better to have an adversarial system, where any votes coming out of the ballot box are observed by representatives of all candidates. Each candidate has an incentive to ensure that the others do not tamper with the vote.
