I don't see what the fed are describing on that FAQ as being any better than online banking through a regular bank account to be honest.
I think so, too.
Except maybe for this angle.
With a US CBDC, paying with it would be like paying with a debit card.
But if you could accept payment from one, then it is like you having a merchant account. This would be a big deal, since it would give everyone the equivalent of a merchant account, which otherwise is a huge hassle and difficult to get in the US.
This is a hurdle for CBDC being implemented in the US, however. Since Visa and Mastercard (etc.) and associated banks get a large amount of money for being in the middle of such transactions, if they were to lose that, they would lobby hard against CBDC.
But, in the US, CBDC would supposedly be administered by private entities -- probably then banks. Maybe using your CBDC to accept payments would incur substantial fees (akin to merchant account transaction fees), in which case it would perhaps not be lobbied against.
Any future digital currency must be able to work offline, we have observed cash rising in importance in scenarios such as disasters where internet connectivity is problematic or non-existent. And anonymity is not just about privacy, but the shear number of transactions we'd have to monitor would be phenomenal. Monitoring larger transactions (say over $10k) is expected to meet anti-laundering/anti-terrorism laws - but monitoring all those little $1 stripper tips... hell no.
I don't think the US would care that much about the offline aspect. Folks are used to credit cards as the way to buy everything Any disaster big enough to take out credit card transactions has tended to take out telecoms, electricity, transportation, policing, civil order, etc., and folks aren't transacting in cash then either, as it just devolves into looting, being stuck in or on a house and needing rescue, etc.
Also, transaction load is already handled for credit cards for everything, from $1 on up. Costco, supermarkets, appliance stores, restaurants, gas stations, doctor's office, dentist, etc. -- all in-person payment is mostly credit card transaction. If strippers get paid in cash (and they probably can accept credit-card payment, too), it is probably mainly because folks don't want the transaction recorded on a bank statement for others to see later. Or for government to know you owe taxes on it.
The perfect solution would be some sort heavily encrypted token stored on a hardened hardware device. But quantum computing will always make even that questionable.
I don't think it would be popular in the US. Cards would get stolen. They would get run through the washer and dryer or stepped on and broken. I think folks would want it to work like a credit card instead. That's what they are used to. Also, the government would want to keep track of every transaction.
Also, if you can get rid of paper Federal Reserve notes, you get the ability to deploy highly negative interest rates, as there are no bills to take out to get at last a zero interest rate on them sitting under your mattress. Or you could do a stimulus that goes away if it isn't spent by a certain date. Or you could disallow use of stimulus or other cash to buy certain things. Or you can automatically doc someone's cash for alimony payments or if the government or some government-linked agency thinks you owe money. Or more Orwellian/Chinese if you aren't being a Good Citizen.
My guess is that Americans will be highly resistant to cash being outlawed or going away completely, even though they don't actually use it that much.
But then I never would have guessed that stuff happening in 2020-2022 would ever happen here.
