People wouldn't elect others who are clearly not active. An other point to consider is, that the user base of the wiki changes from time to time. People leave and new one come. The users who do a good job will keep the rights, the ones who doesn't do a good job will lose it. If you are inactive, you don't need the tool anymore, so you will lose the tool, if you are active you will keep it because the this will surely be the case in re-elections. That would look bad. This system is not only to get rid of the inactive users, it shows also if you are trusted. Only people who cling to their tools won't go through a re-election.
