True. But where I'm from you can vote by mail and in person, and if you do, your in-person vote cancels your mail-in vote. This means that even if someone coerces my mail vote, I can still override it on election day by showing up in person and vote in secret.
...and if whomever is coercing you to vote a certain way can also prohibit you from voting in person, you have bigger problems that border on kidnapping and illegal captivity.

Nonsense. You have whatever problems made your vote susceptible to coercion in the first place, no more and no less. It's not necessary for the other party to physically prevent you from voting in person. All they need to do is observe whether you do, and punish you accordingly.

Yes, but this doesn't scale, and again, it's bordering on illegal captivity. One person can maybe prohibit a couple of others into not going to vote in person, by living with them.
Whereas if you have paper receipts that show what you voted for, one person can easily validate thousands of those, and punch everyone in the face who voted "wrong".
It does scale of course. The one example you mention is couples. Perhaps men prefer one candidate over women and pressure their wives to vote a certain way. How is that not scaling?
Another example is unions. Perhaps the union and many colleagues prefer one candidate - if you sneak off to the voting booth you risk ostracization.
