I don't need to compress anything either, but zips/rars are good for getting around other types of limitations. For example, splitting a collection of files into chunks to send one by one or to increase copy speed. As an example, my archive of downloaded comics takes well over an hour to copy onto a drive as file folders, but as a single archive file it takes only a few minutes and I can unzip it on whatever device I'm putting it on.
