You are making the assumption that the information quantity is a good measure of the complexity, which is far from obvious. It is also wrong in general for the genetic code (for example, many organisms have a much bigger genetic code than human, even though they are arguably much simpler - e.g. rice has more encoding genes than human). Also, having a few set of simple rules is not enough to understand or reproduce a system in general.
