consider this:
"Money is not fundamentally a commodity medium of exchange that made exchange more efficient compared to barter, but a particular form of credit, a system of clearing accounts (transferable credit)"
if so
"the 17th century philosopher John Locke has a lot to answer for"
and
" money as credit is inevitably social,...... its value bound to be politically determined."
" In a financial crisis, when the size of debts begin to encumber the economy
, it is therefore quite logical and natural to adjust the value of money
to redistribute between creditors and debtors"
