The Orwellian nature of CBDCs cannot be overstated. In a cashless society most people would be dependent on digital products for exchanging goods and labor, and this would of course mean the end of all privacy in trade. Everything you buy or sell or work for in your life would be recorded, and this lack of anonymity could be used to stifle your freedoms in the future.
For example, say you like to eat steak regularly, but the increasingly authoritarian government decides to list red meat as a health risk and a "climate change risk" due to carbon emissions from cows. They determine by your purchase history (which they have full access to) that you have contributed more carbon pollution than most people by eating red meat often. They declare that you must pay a retroactive carbon tax on your past purchases of red meat. Not only that, but your insurance company sends you a letter indicating that you are a medical risk and they cut off your health coverage.
Comment: 22 years later, it amazes us that people can still be surprised to learn that 9/11 was an inside job, but everyone learns at their own pace!
