Something I don't understand. What's the point of obfuscation if ultimately you can be caught when you try to convert it to fiat? If I have Btc and I convert it to monero to prevent tracking, how do I get it back to money in my bank account without being traceable?
Let me give you a realistic answer. There are soft and hard criminals. For example: soft criminals buy drugs, hard criminals sell drugs. The soft criminals convert from traditional to digital money (plus maybe a little obfuscation), order and hope for the best. The hard criminals have to solve the difficult problem of reversing that conversion. They'll just have some homeless person open a bank account and then use that for the conversion. If the homeless person gets busted, it better keep its mouth shut - or else.
