It is a very valid argument against data collection for the sake of data collection, which is closely related.
Can't find the exact source, but there was this story about some French (?) town keeping a list of Jews in their documents, for no real reason. It's a piece of data - better to have it than not, right? Might be useful some day. Nazis certainly thought so when they occupied the town and got hold of the list.
The Nazi's weren't enabled by a database. They wouldn't have been stopped by the lack of one. And they certainly didn't care whether or not the the people they killed were actually Jews.
