It already exists in South Africa, just not in the same framework as a CBDC.

i don't want to make a long post but ultimately direct currency from the people who hold the reserves is better than currency from banks who create it from nothing.

This is the thing about currency, it's highly swappable and has its use cases. When you travel, you need cash of that location, so you get currency or your bank doing a spot trade of the purchase amount and charging you conversion fees and an premium on FX.

Now if cbdc's exist, we the public, can get currency directly from the central bank (without a fee) and just an FX trade of other currencies against their CBDC or crypto reserve.

There is obvious pushback from the banks because this cuts them out and they are mafia
