Apathia this is a beautiful post.
Let me correct some of your interpretations of OM.
There is no such a thing like "atom" for Simplicity and "atom" for Complexity in OM.
There are opposite atomic aspects (Non-local or Local) that enable Complexity as a result of the linkage between them, such that the identity of the opposite atomic aspects is saved during linkage exactly because they are derived form atomic self state, which enables them to be linked without contradicting each others identities.
According to OM's view Complexity is possible exactly because it is a manifestation of a non-destructive linkage between opposites (where under non-destructive linkage between opposites the identities of the opposites are not eliminated, otherwise there cannot be any complex phenomenon, abstract or not).
You still miss the exact nature of this linkage, where two opposites are not only independent, but they are mutually independent of each other, where mutuality is their common atomic self-state and their independency is their unique identities as opposites.
OM is not less than the common and the unique as a one realm.
Community or some individual of that community are already complex phenomena (a community is based on persons, and a person is based on his biological complexity) so OM asks: What enables Complexity in any given scale level, whether it is at the level of civilizations or at the level of a single hydrogen atom.
These notions are derived from direct perception, which is a pre-linguistic state that enables language, but I explicitly said that silence is not the word (or thought) "silence", and this distinction is essential of OM's understanding.
Please read very carefully
http://www.scribd.com/doc/17039028/OMDP and try to get the core (the direct perception state).
As long as you omit direct perception as OM's main principle, you don't get OM.
To be interpenetrated and integrated is already a state of Complexity, but OM goes deeper in order to find the foundations of Complexity.
You claim that such organic goings on are much messier than an attempt to mathematize ethical concepts.
Ethical concepts are also a form of Complexity and so is Math and Logics.
OM is a tool that is used in order to fundamentally get Complexity, and it is done by direct perception, which again, it is a pre-linguistic state that enables any mental expression, whether it is Empathy or Logical analysis.
By OM heart and head are a one organic complex thing.
