Volatility is not the enemy, but claiming that a proof 'creates' an equivalence is a dangerous simplification of reality. A proof establishes a condition or a relationship; it does not generate it in existence, because it already exists or not. We must understand the asymmetry of risks: security is the real risk if we do not test the limits of such equivalences. For example, extreme geopolitical shocks could introduce non-linearities where the equivalence would become untenable, despite the mathematical proof.
