You're missing the point about IDs being incredibly easy to obtain. They are not in the US. Additionally, there's a long history of using voting requirements to disenfranchise voters.

I can't comment on the countries in the picture you've linked. I'll guess that most or all of them make it both easy and required to have a national ID card. That is not the case in the United States.

Consider a working class non-driver who has never travelled overseas. What is their ID?

Would you propose a new state or federal ID card? Great. How likely is it that the state or federal government will produce a system for issuing these that is easy to access, widely available, free, quick to issue IDs, etc? How likely do you think it is that politicians will attempt to modify the system for issuing these IDs so that their opponents' voters will find it more challenging to receive them?

If your answer is "likely" and "unlikely" respectively, you are naive to the history of voter disenfranchisement and vote-system-gaming in the United States. Much of it is based on race.
