> If you want to get all dogmatic against stuff like laws against money laundering, come up with an effective alternative

No, it's not just a matter of alternatives: it is also a matter of principles.

For example: in europe, I am unable to make online purchases with electronic money, as all the payment devices are tracked, matched with a personal identity - they cannot be unidentified as they could be only a few years ago. There existed occasional cards for online shopping - now they ask you a local telephone number, identity tied. This under the excuse of "countering money laundering". So there you have "privacy" vs "financial monitoring" - with immensely disproportionate effects in a farcical manouvre.
