This seems very optimistic to me. I’m reminded of the xkcd where the cryptography enthusiasts imagine that 4096-bit security will protect their secrets, but in reality no one bothers with that. If the government requires ID for crypto purchases, they can shut down businesses that don’t comply. Businesses will comply. The tax agency can audit you and see if you have nice stuff that’s not accounted for. If you have a significant source of income from unreported crypto, this will likely be evident in many ways — business relationships, web presence, letters in the mail. Very few people can actually turn into ghosts, even with crypto.
