More so, any system of rules that was anywhere near complete enough to deal with every situation ever would be so huge and complex that no human could ever read and understand it all, and even searching it properly would be impossible. Which will certainly lead to parts of the rule system contradicting each other and actual cases following one or the other or something else entirely depending on what the person applying it to the case was able to find. And if some individual's ability to find things or not decides what happens, then we're right back where we started, at a rather arbitrary system vulnerable to corruption. In which case, why did we even bother making this huge incomprehensible set of rules? See for example the US Tax Code.
