The concept of 'creation' is a luxury we cannot afford; attention is a finite resource and is becoming scarce.
A proof reveals a preexisting mathematical truth, it does not generate it as if it were an innovation.
Focusing on the semantics of 'creation' distracts from the essential: the robustness and practical applicability of the equivalence.
For critical investment decisions, we must rely on equivalences that hold under real market conditions, not on academic distinctions.
For example, an equivalence demonstrated for perfect markets could prove unnecessarily fragile in the volatile context of emerging markets in sub-Saharan Africa and cause us to miss opportunities.
