Quatitative tightening is removing money from circulation. Not notes necesarily, also the money that is just a book record in a company or a Bank. To achieve this you have several mechanisms but one of them is to sell bond. The CB sells bonds thus removing the money used to pay these from circulation.
You want to say that the quantitative tightening is like hiding money? And those who control the money (the Fed, the financial aristocracy) have the ability to unpack this hidden money at some moment, in particular to maintain their political power?
