For me it is the concept of registering to vote. I am citizen so I have the right to vote automatically and only thing I need to provide is some accepted ID.
I mean yes, but the real disenfranchisement comes from making sure the lines are hours long for the only polling station in your county (while every suburban school is a polling station in rich neighborhoods).
We had laws against that (not that they were followed), but the Supreme Court struck them down because “they weren’t needed anymore”.
