Edit~hey gang, when I posed this question and had some opinions. I realized I don’t really feel one way or another about it and I can’t really articulate a stance (probably just too tired). I won’t be engaging. I don’t want to just delete it though because some people made interesting points. Up to mods what to do with this.
No, it reduces the effort needed for corruption.
The smaller the circle of power is, the less effort is needed to corrupt the entire system.
Also, it would prevent experimentation. Trial and error is an important method of finding out what works. One governing body would have one set of rules, we would never discover if a better set of rules exist.
Who says one governing body means only one set of rules? What if one governing body kept different rules for different areas?
