Guiding Answer: Lets look at the article:
We can see that it shows the pros and cons of each already, and who will benefit most, and who will not. As we look, we see if we go cashless, the poor communities will suffer the most, while credit card companies will have the largest benefit. One scary idea that I can think of, is cashless payments, it will be easier to hide secret fees, that with paper money, will be much harder to mask. We have also have to make not of the fact that there are literal millions who have no access to bank accounts. We can read that in this quote:
"And on another side are millions of Americans who lack access to bank accounts, as well as poor and rural communities with few if any branches serving residents and local businesses. Many of them rely on cash for commerce."
Also, this quote shows that cash isn't as dead as people think it is:
"Despite the increased popularity of credit and debit cards in recent years, cash still remains one of the most popular ways to pay for things in the United States, accounting for 26% of all payments by consumers last year, according to data compiled by the Fed. Spare change and dollar bills are still overwhelmingly favored for small purchases, accounting for about 50% of payments under $10."
However, we have to remember this:
"Paper currency in the United States is made from 75% cotton and 25% linen, according to the Treasury. That makes the surface of bills coarse and fibrous, allowing germs to adhere more easily and survive longer than they can on smooth objects."
Thus, novel corona-virus can stay around in the paper cash, which can be a problem, albeit, the CDC is unsure how much it actually is. To also quote some banks:
" Representatives from some lenders think it’s important for regulators to offer guidance on handling money, noting the risk of using currency is low — comparing it, say, to pushing an elevator button or grasping a handrail."
As you can see, each side as it's benefits and cons. Read, and build your own opinions from facts.
Here are some bonus Quotes to help you:
"If, on the other hand, authorities take steps that discourage the use of dollar bills, it will buttress the credit card industry’s long-running “war on cash,” sending more transactions through their networks and to payment apps that collect fees. That could even boost interest-bearing credit card balances."
"“Digital payments are already viewed as good for society by governments because they help with financial inclusion, they drive tax revenue and eliminate corruption,” she said. “This is another reason: ‘Oh, and it’s hygienic too.’”
"“Going cashless is definitely not something that we particularly support,” said Eric Espinoza, an associate director at Neighborhood Trust Financial Partners, which helps provide financial services to low-income communities. “We certainly wouldn’t support it under a hasty decision-making environment in which you’re extremely reactive and potentially not as thoughtful about the repercussions.”"
"Roughly 25% of Americans are either unbanked or underbanked — with black and Latino households making up the largest percentage of those lacking accounts, according to a study by the Federal Deposit Insurance Corp. More than half of unbanked households in the United States say they lack the funds to keep an account open."
