Yes, but I still don't see what difference the word 'ontological' makes in this context. Surely whatever world-conjuring power numbers may possess can't depend on which label is attached to them? If a mathematical scheme fulfils a deep enough explanatory role (a moot point I admit) isn't that 'ontological' enough?
