Leaving aside everything else, using the rule of St. Benedict and pointing out its influence on medieval thought seems like poor choice. Benedictine monasteries were often notoriously corrupt. There were frequent attempts at Benedictine reform, but it was almost always that case that in a few decades, the reformers would become more corrupt than those they were initially criticizing.
And, of course, is medieval government actually something to aspire to? Medieval European governments were extremely unstable, collapsed frequently (often due to assassination), rarely went a decade without civil war/armed rebellion, their legal systems were patchy and inconsistent, and almost all of them had laws which separated punishments for commoners and noble-born. The fact that medieval law was influenced by the Benedictine rule seems like a reason to reject it.
