Giving someone the ability to vote to kick someone is practically giving them a staff rank. You're instilling some trust and authority in them. It will go to people's heads.
Yes they do have some sort of authority but that's as far as their powers will go, and besides this change is definitely in our favor. If we grant a power like this to people who we genuinely believe will put it to good use, there will be less disruption across the board when staff is unavailable. We can either make it so every player online can vote on a person who these regular players want to kick (and trolling cant exactly occur in this case) or we can make it so once the votekick is initiated only other regular players can vote (a minimum of 3 need to be online).
