It's not the concept of a diff that baffles ordinary people. It's (a) the lack of an intuitive interface, and (b) poor integration with natural languages, that make most VCS's difficult to use in the context of a word processor.
Word shows pretty bubbles next to sections that have been edited. The bubbles are color-coded so it's easy to tell who did what. The edits can be accepted, rejected, or further modified with a couple of clicks. There is no list of commands or keyboard shortcuts to memorize. Just a bunch of icons, menus, and clicking around.
Word doesn't require your content to be made up of neat lines of verse, either. Natural languages don't organize themselves into 78-char lines. It should be OK to edit a few words in a long paragraph of prose. Even Wikipedia's messy "Revision History" is probably better than git in this regard.
