There's plenty of countries where neither of those is true, but the voting system requires a national ID and has better outcomes by any reasonable metric than the US. So you don't really need those things, but they may be proxy issues for other hard-to-solve issues.
I am not very familiar with the systems other countries use so I am genuinely curious which ones you are referring to here and whether they are comparable to the US. The US has a centuries long history of laws designed to make it harder for "undesirables" to vote. The US's racial and socioeconomic makeup and its history of oppression of those groups makes this a much more contentious issue than some other countries t…
It's the same sort of thing in most European countries, you need to prove who you are, and usually doing that costs some one-off nominal fee. Voting is always going to carry some cost, whether that's money or in externalities imposed on voters.
I'm not saying Iceland and other European countries are "comparable to the US", I'm sure we could spend all day moving that particular goal post.
I was just pointing out that there's nothing wrong per-se with requiring ID to vote. I'm somewhat familiar with the US history on the matter, and realize that in practice, and I think uniquely in the US, it's a wedge issue that's historically been motivated by voter disenfranchisement.
But it's important to separate that practical concern about particular implementations from the very notion that having a national ID system and using it for things like voting could never work.
I'm curious about how this works in practice. If you're a tourist visiting the US during a vote can you just show up to a voting polling station and cast a vote? If you don't have to show your ID what happens from the time you walk up to a polling station until you cast your vote and walk out again?
