BTC indeed tries to simulate CASH for CASHLESS transactions.
You are not aware what CASH is. Cash is not only bills or banknotes. Cash is every form of money (in paper, metal, wood, digital or whatever form) that you can instantaneously spend without increasing anyone's debt!Call it as you like. The "cash/change" simulation is not my idea.
btw:
Debts and claims as juridical things have nothing todo with the relative items claimed or debted.
Apples and a claim or debt of apples are quite different things.
With money and anything else its exactly the same.
Money is money and an apple an apple. Not a "debt" as sometimes insinuated.
