IMO the solution to that problem is to not rely on the money as evidence to investigate crimes. Back when people used cash for everything, criminals were still caught. And I don't have a source but from my view, the rate of crime actually being stopped has not gone up with the rise of financial surveillance. I'd be surprised if someone could show me that that's happened. So, the solution is, give everyone private money and make the cops do their job and investigate. If the trade off is any fuckhead I bought a ps4 controller from on Craigslist can figure out my net worth and crack me over the head and take it, but *maybe* some drug dealers will go to jail and *maybe* the CIA won't have a black budget, that's not a worthwhile trade off. If the trade off is some drug dealers get away but in safe knowing nobody but me and those I volunteer to tell know what I have, I'll take that. And, IMO, the black budget problem goes away, because they can't just print money, they have to take it from us to use it nefariously in the first place. They can borrow it, but without printing, they have to pay it back eventually at full price instead of devaluing what's mine and paying it back with the value I lost. So in my view, algorithmically predictable supply solves the black budget problem and there becomes no need for mandatory everyone-is-naked transparency.
