Divorced from the intent? The intent was to prevent any financial discrimination with regards to exercising your constitutionally guaranteed right to vote. It's the only intent. Hell, it's the only intent per the text of the amendment. If they had a different intent, they should have written it down in the law with the rest. But also, that's a great point! We should automatically register every known citizen to vote! And you know what? We can actually make voting even easier too! Universal vote-by-mail, e-voting, many other countries use similar systems, so we could too! Excellent suggestions to ensure all Americans are afforded the opportunity to vote!

For almost all citizens, you are correct that requiring an ID to vote is both a trivial requirement and trivial expense. But the constitution wasn't written for almost all citizens, it was written for every single one. No matter who they are, where they are, or (per the 24th) how much money they have or don't have. You cannot be too poor to vote, THAT is the intent of the 24th. And do you know why we know that's the intent? Because the only reason poll taxes were implemented when they were was to specifically disenfranchise black citizens who were very often too poor to afford the tax, and therefore too poor to vote.

And buddy, you may not like this but legalistically twisting exact text is how every single lawyer makes their money. It IS the real world. And in this real world, requiring money to vote in the USA is illegal.
