Insofar as the logical basis for classifying them as "crimes," yes, I am. Not in terms of seriousness or morality, obviously. Also, conflating money laundering and tax evasion shows a serious lack of understanding. Tax evasion can involve money laundering, sure, but money laundering is often the mechanism used to enable far more serious crimes, including, yes, murder.

Many things "enable" murder, including cars, guns, bullets, knives, etc. In any case this utilitarianism is a dead end. If it is not absolutely fungible, it's not money, it's coupons, food stamps, tokens, but not money and will not ultimately be used as such.
