Why would a government trace an Average Joe's crypto activity. i mean there are a lot of more important stuff to do for them
there are tons of average joes who skimp on their taxes, don't pay child support, buy drugs, buy guns and on and on. governments chase millions of average joes every single day. prisons are filled with average joes.
The average joe won't likely have the careful attention to detail to make their anonymity significantly difficult for the government to track them. But default anonymity protections could possibly protect the average joe from casual privacy invasions. And the meticulous joe could probably make it not worth the government's effort to track them given the necessary anonymity protocols in the crypto-currency system.
Unless the anon sector starts pulling billions of dollars per day, the government won't bother--but simply rely on tracking software developed by the private sector. And this is pure speculation, I believe TPTB (Russia, China, US, everyone basically) are engaged in a huge ballet of Agar.Ioesque nature to see who can grab the trillions of dollars that escaped their borders through tax evasion. If they can grab some of that still elusive pie, they can make projections that the economy can grow--the problem is that while they are engaged in real-world strife with actual human costs--the digital world is programming a more efficient world that uses cryptography to create escape points of value--symbols are taken from the old world system--commands, and literally to figuratively to latterly-reassembled--cal's about to reinvent the game and standford's band is on the field....
