A reputation system to replace courts? I highly dislike this idea because the point of courts is to judge people based on evidence and objectivity and to specificly ignore subjective factors such as reputation.  Someone's reputation can be strongly affected by hearsay, gossip, superstition, moral panics, prejudice, hysterical media, and the like.  That would be a world in which, de facto, a popular kid would have more rights than an unpopular kid. The thought makes me shudder.
