@fresco,
Ontological status does not have to be operatively independent....actually I can´t see how it could.
Don´t get me wrong I see what you mean, but different functions in the same object don´t ad to its status, but rather reveal its status in its multiplicity, its operative potential which of course is from a dynamic point of view (along a time frame) relational on per se...
Ontological independence its then applied to the whole of the system in its Hard Deterministic instance including the true value of the entirety of its functions at any given frame of time, and along the whole chain of time/space...
...things or objects although with contingent functions given different possible interactions still sustain their validity in a Hard Deterministic background, if it is the case that Hard Determinism is true, which of course we don´t know...
