Not really, you only need permission when making large edits that involve many page, because if the edits turn out to be unnecessary it would require plenty of work to undo them. Small edits like adding a missing category, creating a page from a Red link, fixing typos, ect. don't require permission.

The idea is that anyone should be allowed to contribute, this "permission" thing is just to avoid dealing with having to do lots of edit-undoing at once.
