The CBDCs certainly can expedite their money printing and any outright theft outside money printing they have planned. In addition they have much tighter control over you in several ways a la the Chi-com social credit score system. One question I pose to you is what about those who don't have phones or computers? Do they screw us again by having our tax money pay for phones for everyone? I know they are doing that now, but under the new system it would literally be everyone.
I was pretty surprised when Gammon said they did not want smaller bills. I would think smaller bills would be preferable to make change. I guess not. I know when Jeff Berwick went to Venezuela a few years ago he had to pay for lunch with a backpack full of local paper.
Per another of your points - the businesses adjust and set up their money flows around whatever is in place and it is sometimes better to maintain than change. Not to mention yet another thing you mentioned - the perverted system creates entirely new businesses set up around the system being perverted and those business owners do not want change because it puts them out of business as you noted.
It is truly tough to hedge all this but diversification will soften whatever happens. Stack, buy shares, buy physical things you think you might need that might be expensive later, try growing more of your own food, defense items, canned foods and whatever else gives you peace of mind. If I spend a few thousand and nothing happens I will have zero regrets. Actually, I hope nothing happens.
