"Money ... has something in it sacred that is not to be sported with, or trusted to the airy bubble of paper currency." (Thomas Paine, 1737 - 1809)
The Lord hates dishonest scales (including fiat currency), but accurate weights (like gold and silver) are his delight. (Proverbs 11:1)
The silver is mine, and the gold is mine, says the LORD of hosts. (Haggai 2:8) The borrower is slave to the lender. (Proverbs 22:7)
The wicked borrows and does not repay. (Psalm 37:21) Righteousness exalts a nation, but sin is a disgrace to any people. (Proverbs 14:34)
Since men did not think it worthwhile to retain the knowledge of God, He gave them over to a depraved mind, to do what ought not to be done.
They have become filled with every kind of unrighteousness, fornication, wickedness, greed and depravity ... they invent ways of doing evil ... 
they not only keep doing these things but also approve of those who practice them. (Romans 1:28-30,32)
Because they did not receive the love of the truth so that they might be saved, God will send them strong delusion, that they should believe the lie. (2 Th. 2:10,11)
