The currency will be inflated, not reset. They want M2 to become M1, the banks will loose their liquidity. So another obstacle for small / regional banks, and another excuse for central banks to expand their balance sheet. The control aspect is further down the line, only once CBDCs are well established, and under the pretext of some emergency. Maybe with a competitive stablecoin market, this is less of a risk. Although your savings will be devalued anyways.
