Privacy is the tip of a very nasty iceberg
I may seem something of a luddite here but bear with me. If I'm not mistaken we already have numerous & very effective ways to make cashless transactions should we so desire. Bank transfers, cards, even apps all exist for exactly that purpose and by and large function well enough that they've become accepted in society for daily use.
Cash is different. Physical cash is exactly that - a physical, immutable representation of wealth. If you hold it, you have it and it's yours to spend as you see fit. If someone wants to take it off of you then they need to physically confiscate it, a process sufficiently complex and time consuming that it's intrinsically resistant to abuse. It's not practically traceable and has no privacy risks. You can't hack my wallet from a bedroom halfway across the world. You can try and pick my pocket if you like but that carries a distinctly non-zero chance of you getting a punch in the mouth and quite possibly jailtime which again tends to limit the risk involved.
If the bank is closed (or worse, bust) then the cash in my pocket is still mine. It still has it's value, I can still spend it, at least for as long as other people agree it has value.
Now, replace that with a CBDC and a 'digital wallet'. Instantly all the advantages of cash are gone. Digital transactions are traceable, so no more privacy (anyone saying anything else really needs to go look at some modern history!). It's only 'yours' for as long as the bank say it's yours - it can be blocked or invalidated at any time, easily. Pissed off the government, no more money for you. Voted for the wrong party? Said the wrong thing? Spent more than you should on 'bad' things? Same result... what you thought you had, you don't have. That 'digital wallet' can be and undoubtedly will be hacked eventually - everything is.
For central bank transactions, perhaps it's justifiable BUT there are already plenty of solutions for that... it's not the driver for this.
In short, CBDC is not a solution to any problem faced by normal individuals. It's at best a waste of time and at worst a tool for total control & oppression on a scale never before seen.
The privacy issues are the tip of the iceberg.
