Am debating what are the innate properties that constitute money. For the reasons stated in prior posts I do not consider privacy to be applicable to what makes good or bad money and do not see that as a factor towards driving adoption.
Privacy is not necessarily a property of money. Fungibility is a property of money though, and without strong legal guarantees of fungibility, it likely does require privacy because if you can trace "bad" or "good" coins then fungibility isn't there. Bitcoin currently doesn't have whitelisting/blacklisting, etc. (for the most part; there do seem to be some exceptions involving Coinbase, etc.) but as long as that concept is in play fungibility is a question.
