Isn't a vote being verifiably tied to a person actually a bad thing? Then you can actually check what e.g. your wife or kids voted for and punish them if they vote wrong. Or get people to pay for votes, but doing that at scale is obviously hard.

Maybe this isn't what you meant by verifiable, but there are systems with this property and they are bad.

The property you are talking about is generally called "deniability" in the literature, whereas the GP is talking "verifiability" ie. being able to verify your own vote is cast correctly. They are both valuable, sometimes mutually exclusive, but not necessarily, see eg. https://petsymposium.org/popets/2024/popets-2024-0021.pdf

Verifiable in this context means I can verify my vote was tallied correctly.

That would also mean someone could force you to show who/what you voted for.

Receipt-freeness (i.e., a secret ballot) is usually the desired property. Yes, a lot of people like you state they desire verifiable votes. But that's where you need to respond to the points the person above you is making: how is such a system not also susceptible to coercion and bribery?

(However you would verify your vote, imagine the person who is coercing you is just standing over your shoulder with threat of force. An example might be an abusive husband who does not want to allow their wife to vote freely/against him. A briber might simply force you to allow them to look over your shoulder before they'll pay you off.)

Vs. paper ballots in a polling place: a coercer would not be permitted in the poll booth with me. I get to vote, and when I leave, … I can tell them whatever, but it does not need to match my vote. It utterly defeats bribery, as the briber has no way to verify that I'm doing what they way.
