I will speak from a personal experience that yes, if you go and edit a "friend's" userpage, it will get deleted if they have no active contributions, or anything constructive. However- I will admit your whole "permission" thing probably sounds okay because I've edited grammar issues or coding issues on friend's userpages and have stated in the edit, or went directly to Kevin telling him I've been given permissions. Additionally, I have a nice little bit giving certain users permission to edit mine. C:

But in most cases, the point still stands that you shouldn't be editing or creating pages for people who don't work. I've edited pages for people I don't even know for simple coding problems and stated why in the comments, but this person has a history of contributions, as well. Maybe when your friend comes back and works on the wiki, he can get his page back.
