Humans don't 'need' math-based cryptocurrencies when dealing with other humans. We walk slowly, talk slowly, and buy big things. Credit cards, cash, wires, checks - the world seems fine.

Cryptocurrencies are an emergent property of the Internet - almost a fifth protocol in the Internet suite. If Satoshi Nakomoto did not exist, it would still be necessary to invent them.

Cryptocurrencies like Bitcoin are already trustless - any machine can accept it from any other, securely. They are (nearly) free. They are global - no central bank required, and any machine can speak the language.
