I read the story about money some time ago
It say, back than people use gold and silver for transaction, because it heavy and not safe for travel, night temple / now Jesuit, offer you a note, put your golf in Jesuit bank, you get a note for travel, it was pilgrim to Jerusalem, there you can go to Jesuit bank and exchange it back to gold money.
So money was certificate or prove that you own gold in the bank.
So every bank was permit to issue money and own gold as backup.
Now Jesuit slick, monopoly to print money in the name of federal reserve, without gold as a backup.
Print money from thine air, loaned to us government and tact payer pay the interest, no wonder Vatican so rich robbing people money behind the screen
