On one axis put (potential) individual liberty and anonymity. On the other put health and safety and access to material comfort. I suspect there is an inverse correlation to some degree. 10,000 years ago you could do whatever you wanted, up to and including murder and as long as you were fast enough to escape those seeking revenge you were good. Even 100 years ago you could change your name, move to a different country and start your snake oil business (or whatever) fresh and it would take a long time for justice to catch up. Life was not highly controlled like it is now. There was always a place to flee, always the opportunity to escape. Most people farmed and eked out a living and their hours and activities were dictated by little but the seasons. Not now. You will be at your desk and 9:00 and go home at 5:00 and eat lunch for 1 hour at noon. There are million little rules for everything. We spend all our time following them (or not, but the consequences are more consistent and there is no place left to run).
We accept this trade-off because it enables us to live longer healthier lives with more material comforts. I'd venture a primitive person from 10,000 years ago would scratch their head and wonder why any rational person would do this. Smart phones are a more recent example. Who in their right mind would carry a tracking, listening spying device? Well, anyone who wants instant access to information and a guide to the other side of town, obviously.
Point is this. We give up what we consider liberty for efficiency and this has been going on for thousands of years. These currencies yes will track, yes maybe can only be used for certain things, yes allow a high degree of control. But what if they make the flow of goods and services more efficient? What if they help eliminate ruinous market cycles and depressions and poverty? What if they completely neuter corruption and large scale organized crime? Do we accept them then? Probably we do.
Just to be clear I don't like the idea either. But probably efficiency wins irrespective of my personal biases and life is on the whole "better" for some definition of the word.
