Anonymous money flows aren't illegal. There are those that would like to make them illegal, but all they've managed to institute so far is KYC/AML laws relating to third party payment processors. These laws don't apply to cash or its electronic corollary, cryptocurrency. Until a law is created that makes unmonitored use of physical and electronic cash illegal, anonymous money flows aren't across-the-board illegal. One obstacle elitists have in instituting such laws is that enforcement would be costly, involving heavy-handed treatment of large numbers of end-users. Trusted third parties like banks are comparatively easy targets, being much less politically costly to repress.
