Git is not just about git diff. For example, it gives you the ability to find which changeset introduced a regression by doing a binary search on the history and running tests automatically on each revision. The culprit could be a change made months ago. To do so on an IDE with local history, you'd have to Ctrl-Z backwards all changes (not meaningful commits, but even small changes) linearly.
