So what's your obsession with having a non-human leader and enforcer of divine law who is not God but flawed ignorant kings, with high priests, lawyers, fines, absurd rituals, sanhedrin, prisons, etc.?
Excellent!
When you read your Prophets in full context, which you never do, you will discover that the arrival of Moshiach will be accompanied by a full recognition of God and everyone will automatically know and fulfill the Commandments.
Then again, I'm asking a lot for you to actually read anything in context when you're so dependent upon a supernatural being to constantly absorb all of your purposeful mess ups.
