CBDC is simply a vehicle of commerce that gives the controllers, central banks, unlimited and over bearing control on all people. You wont be able to buy a $0.05 book at a a garage sale without being permitted to by the CB or without paying them fees and taxes. Essentially, it ends the free market for civilians. Firearms? No you cant purchase those. A Corvette? No silly, there are no budget supercars anymore you will have to save $300,000 for a Porsche or drive Nissan Leaf.
