I would argue that it depends on the Cryptocurrency you are looking at. While yes, Bitcoin has almost no privacy when it comes to watching a transaction take place from Address A to Address B, if you look into the white paper of Monero [0] or ZCash [1], you will find that they are almost impossible to trace from a technical perspective. They have essentially solved this problem and you can achieve full privacy and anonymity. If Cryptocurrency takes off and society accepts it enough to take it as a ordinary medium of exchange, I would imagine it would almost be impossible to prevent people from routing a subset of their transactions through privacy coins.
