Many communities would lose out on edits if every unregistered editor was unable to edit. However, if it was made that all unregistered users just shared the same designation, it would be impossible to administrate a wiki, as you'd be unable to block any unregistered users who may be vandalizing pages since you couldn't see who's doing it. If someone wanted to go cause problems for someone with an IP address, they could just as easily pick an IP at random via number generators.
