Don't forget about the witness vote expiration, which is a good addition to the security. A witness cannot abuse a vote, he have got from a user who don't check the witness' works and intentions after the vote, more than 3 months. So active users can take the chain back easier from traitors than if a lot of inactive users' votes would stick to the corrupt chain.
