I have to object that the rule of law isn't about the extent of laws and enforcement but rather about making whatever enforce exists systematic, fair and so-forth. The concept of rule of law never implied the replacement of custom with bureaucracy - although that often happens. It implied the replacement of the venal authority of kings and nobles with codified principles. Especially, as the parent points out, customary honesty isn't based on any enforcement system.
