Surely there is a middle ground between "every single transaction that has ever occurred in the history of the blockchain is public and visible to all" and "no transactions are ever visible to anyone including governments investigating crimes that have exercised due process in obtaining warrants and subpoenas".
Electronic money of whatever form is equally trackable regardless of the value of the transaction. That forces a world where either you can drop country-destabilising quantities of money anywhere without any law enforcement or every microtransaction ends up in the security services database.
Anonymous billions are all fun and games until the second plane hits the tower.
What? security services can only spy on money, but just can’t do their main job of preventing attacks by humans?
Maybe we should hire a competent replacement for that job then.
