Man of Steel

Your client asks you to calculate the monetary value of Superman if he were a real person operating on Earth. Superman protects only the USA, faces four competitors with similar abilities, and acts on his own during crises. Your goal is to estimate his value considering his extrinsic and intrinsic impact, focusing on a few key factors such as security contribution and crime reduction.

Estimate a plausible monetary valuation of Superman based on his extrinsic contributions to US security and associated impacts.
