There's no need to go to the trouble of making these changes. Cash money has been illegal in the United States since before most here were even born. If they discover you have cash, it can be confiscated (and charged with a crime... not you, but the cash can be charged). If you deposit more than $10,000 at a bank, the banks are deputized to snitch on you. If you deposit exactly $10,000, they snitch on you. And, because some criminals might deposit less than $10,000 to try to avoid consequences, if you deposit less than $10,000. Not just banks, if you bought a new car (or new RV, or new tractor, etc) at a dealership with cash, they'd have to report that too. Social norms have been subtly manipulated to convince you that people who have cash or pay with cash are shady.
