So maintaining the 'justice system' is an ends in itself? Why should I care whether or not the government has a particular department?
There needs to be a systematic and reasoned standard way for people to have redress of grievances, which does not take things to excess.
Having this be handled by the government seems to be a reasonably good solution.
Having people handle things themselves isn't reasoned or systematic or standardized and does tend to excess, and is bad for everyone. As tends to be demonstrated fairly clearly every time it happens.
If the current system of having the government handle this collapses or loses people's trust -- assuming this isn't due to some better system being implemented -- it would only leave people to handle things however they feel, and would be rather harmful.
