What's the point then, of using a mixer, when your funds can be traced so easily?
I'dn't say it's easy, it takes a lot of effort including tracking down criminals first. An address can't simply be a means of identification without finding the person and then investigating whatever they have. In other words, criminals are the first target, then mixers are second. If the mixer is in first place, then global regulations will close the existing mixer services regardless of whether they've been involved in money laundering or not.
