Ah, I thought this was about another kind of secrecy emphasized in the article:
We don't just need votes to be anonymous and private (while still making the final result provable and public); we need votes to be so private that even the person who made the vote can't prove to anyone else what they voted for. [emphasis theirs]
This is the part I was saying doesn't seem so necessary.
I think that goes along with what the parent mentioned. If someone can prove how they voted, then Person A can buy Person B's vote and request proof that Person B voted that way. However, if Person B can't prove which way they voted and it is just based off trust then Person B can lie and still vote however they'd like.
It's a really nice property to have, though-- often on the path of authoritarianism is being threatened and having to pass various kinds of loyalty/political tests... if you could prove your vote this would just help that along.

You can do that today. You could have sold your vote in the 2016 election. It just doesn't seem to be a thing people do.
How can you do that today? Can you get the equivalent of a receipt from voting?
One possibility that comes to mind is filling out a vote-by-mail ballot and letting them verify and send it in.
