Why can't you engineer away jerks? I mean, we have democracy, free markets etc. and among their main contributions is to engineer away the effects of bad behavior. In a democracy, you won't get the best decision, but you will get an acceptable decision. In a free market competitors force business to serve the customer.

Similarly, a techical solution which gives jerks a smaller influence seems an excellent partial solution. Sure, you might still need policing, but it isn't either or.
