As you present this argument here is exactly as it is typically presented elsewhere, which is in a vacuum.

The question to consider is: how do the potential issues presented by a tool allowing individuals to confirm their own vote compare with the issues potentially resolved?

In this consideration, it must be included that tools already exist for individual vote confirmation. Snapchat and even just plain-old MMS are two easy examples. Additionally, a widespread campaign to manipulate a vote through bribing voters is likely to be uncovered through other means such as whistleblowers, else the necessary number to effect the outcome of the election is unlikely to be met.

What is the potential benefit? Individuals can verify their vote was included in the final count as they intended. This would even make allowances for human counters who have trouble interpreting a voter's ballot (e.g. hanging chads) can be corrected, plus increases in efficiency, such as adding some sort of automated counting system, can be employed while black box concerns substantially mitigated.

Allowing voters to confirm votes would substantially reduce nearly all vote rigging concerns that relate to the counting of their votes, largely leaving only the issues beyond this, such as voters voting more than once, voters voting in place of other voters, etc.
