Pretty sure the orignal post is a joke, but I think crypto is a bit like a VPN in this way. Sure your bank can see the initial spend. But after that it's harder to see where the money goes. And you have some of the benefits of normal banking systems. Much harder to buy things from far away with cash.
I refer the learned gentleman to, er, the global economy. How much more scaled up would you like?
Meanwhile crypto transactions have to go through a single common blockchain with pitiful throughput. Even the enhancements like lightning are laughably slow compared to the global banking system.
Escobar sold drugs. The margins on that stuff are rather large, allowing for a few inefficiencies.
But I should have really said: cash doesn’t scale down. Escobar can put people with briefcase on planes to pay his suppliers on all continents. But any smaller outfit would struggle with those logistics.
Doesn't cash do the same thing?
