My thoughts on this are old school. Like 1700's old school.
A person's right to vote exists with or without documentation. A piece of paper, an entry in a ledger, or a row in a database has no bearing on whether that right exists, or should be exercised.
In many of the states where I've lived (13 so far), all that was needed to vote in the absence of identification was to sign an affidavit stating that I am who I say I am. The people at the polling station could ask for ID, but they couldn't require it. It's up to the people who handle the vote (often the county clerk or county board of elections) to decide later if my vote was valid or not.
A lot of that is changing these days as the concept of being constantly tracked, monitored, and tabulated becomes normalized in America.
Just a generation ago we made fun of the Soviet Union and various totalitarian regimes for having police stop people for no reason and demanding, "papers, please." Now there are people who think it's perfectly OK to require domestic passports ("Real ID" and similar) just to walk down the street.
I wonder if two generations from now people will think we're old and crazy because we don't think it's OK for the government to require a chip be implanted in our brains so our thoughts can be monitored by bureaucratic minders.
It's sounds like tinfoil hat sci-fi slippery slopism, but so would today's facial recognition in airports to people just 50 years ago.
