We need one system if we are to avoid one individual mind causing problems for many. Any system if corrupted by just one individual is no longer fully functional. Systems stop working, when changes are made by individuals, whose subjective interpretation of the rules or workings of the system is corrupted for self-gain. When selfish objectives require the system to satisfy a personal criterion this new criterion corrupts, contaminates and dilutes the integrity of the system. A corrupted system then replaces and masquerades as the system but keeps the original name.
