Yes, exactly. I think those wrongdoings should be discovered another way since else, other rights that are more important to me go out the window. Privacy and free speech (since AML or similar laws can be used for censorship) are the first which come to my mind.
However, yes, I am also wondering if that would make it impossible to prevent cases where financial transactions are not good for society.
Someone else in this post proposed to have Gov btc addresses public, so maybe something in this direction.
