It's probably a better system for what to live by. The government can and will imprison anyone they want by a variety of methods they have for putting anyone they want away at any time. If you follow "god's / natural law" as they put it, it is a better guide to whether you will anger some victim who will call the police on you. Most of the rest of the law are just the excuse the powers that be will use for putting you away if the powers that be find you threaten their order. The vast majority of victimless crime laws are selectively chosen to be "enforced" for the actual reason that you've done something to challenge the ruling class, trying to adhere to them as if they are applied as 'rule of law' is probably irrational.
