If that is the point of the justice system, then we really need to reconsider in light of how actual humans behave. It has been shown multiple time over in experimental settings that punishment is a pretty poor means of modifying behavior. The deterrence of punishment is marginal at best. For punishment to work consistently you need to apply it consistently and immediately, law enforcement does neither. There are other means of modifying behavior that are both scientifically proven and have shown results in the real world. This includes accommodating the desired behavior while disincentivizing the undesired ones. If you want the unhoused to leave their surroundings cleaner, give them trash cans, public kitchens, safe use shelters, regular street cleaners, etc. If you don’t want them to pitch a tent on 17th and Mission, designate an area where they can. No the point of the justice system is to give victims of crimes some solace that justice has been served. It has nothing to with the behavior of criminals.
