IT people don't understand:

Law/contracts
Banking
Finance
Accounting
Money

Therefore, they need a standard protocol and data structure.

Communicating transactions without ambiguity

Different cultures and languages create mis-communications in monetary transactions, therefore a standard protocol is necessary.

Some of these mis-communications are perpetuated deliberately and is the cause of wars.

Currency distribution in the United States

Who creates cash and destroys cash? Who controls the cash distribution network in the United States? Who can revoke bank charters and control distribution, terms, and fees all the way to the ATM?

The answer is Janet Yellen, Federal Reserve chairperson.

Examples:

1.  As Janet Yellen controls the bond purchases from the Treasury, she can dictate Congressional budgets (how it is spent/distributed).

2.  As Janet Yellen controls the debt structure and rollovers, she can revoke charters of Wall Street firms, and dictate fee and debt structure.

3.  If accounterfeited digital cash is found in a billionaire's bank account, it can be confiscated and destroyed.

That effectively makes her the "boss" of all Americans.
