From Sapiens: A Brief History of Humankind by Yuval Noah Harari

“Money is more open-minded than language, state laws, cultural codes, religious beliefs and social habits. Money is the only trust system created by humans that can bridge almost any cultural gap, and that does not discriminate on the basis of religion, gender, race, age or sexual orientation. Thanks to money, even people who don’t know each other and don’t trust each other can nevertheless cooperate effectively.”

This is why you can buy off a Taliban war lord or a United States Congressman. Money talks and bull shit walks. And for the most part, money doesn’t really exist:

“The sum total of money in the world is about $60 trillion, yet the sum total of coins and banknotes is less than $6 trillion. 7 More than 90 per cent of all money – more than $50 trillion appearing in our accounts – exists only on computer servers.”

It’s mostly in our heads. Or our collective consciousness, if you prefer. Packed in there with all the other imaginary concepts so many are willing to kill and die for.
