This is another among the issues that have been considering discussing.
We know the government HATES the cash and barter economy. They can't track it unless it's self-reported, hence, they can't tax it unless it self-reported. They also can't always seize money if it's hidden away and not in a bank or investment.
I've been waiting for there to be reports of how someone, probably a cashier, bank teller, casino cage counter, etc., contracted the virus from cash or coin. A big deal will be made about them checking random bills and coins and finding that some ridiculous amount show viable contamination. There will be some really cool graphics showing how the virus lives in the niches and marks or weave (or whatever) of the bill or coin. Hell, I even expect them to say that the virus remains contagious and alive practically indefinitely due to the nature of the base material on the bill.
The answer is obvious: Ban cash sales for the duration (and then, of course, forget to repeal). This would force everyone to use digital currency and bank accounts with the benefit of having every panic-mongering twit screaming to 911 when she sees a cash transaction.
Cash and coins become an Enemy of the State almost overnight.
I would have posted this, but we got rid of that whole Tin Foil Hat Brigade thing.
But, since someone else brought it up. . .
