A couple of things regarding the chart:
1. I still think it is more likely a Ponzi, I only made the chart to show how it could be done as a legitimate but still not legal investment scheme, because the issue was brought up. The two particular Bitcoin-based businesses that Pirate chose to implement very well could work hand-in-hand towards these ends, but it does not mean they *do* work to these ends.
2. I am not making the claim this is a couple million per week, I'm saying it could be a few million every couple of weeks. MtGox alone handled 11.5 million in the last 30 days. At least a handful of estimates stated BS&T handled ~300k coins. These are reasonable estimates based on other's estimates, I'm not manufacturing anything new with regards to the amount of money that could be cleaned via this manner.
3. The title of this thread contains the direction of the discussion, the chart is relevant towards such discussion. Giving pirate the right or wrong kind of attention is irrelevant to the chart.
4. Nearly everyone that has responded saying it is impossible he is doing this does not understand smurfing. Smurfing is exactly why no one ever asks any questions, and a compromise at this level is how a launder will eventually be "caught". Some recent smurfing methods don't even have the smurf know what they are doing, many of them think they are handling financial accounts for online "work-at-home" companies, you've no doubt seen these reports in the media.

It doesn't have to be a huge cartel, but it could be, these guys have millions lying around accumulating, and they've tried real world laundering methods that do not work. They could easily try something Bitcoin-based and not be worse off, but yes, they would very much want more and more business, and it would explain why pirate was absolutely livid when people accused him of a Ponzi. Less interest in BS&T means less profit. But that said, it could just as easily be a Bitcoin hacker or hacking group laundering through him.
6. Many of the people complaining the most about MtGox->Dwolla delays seem to be miners, maybe some traders. Some mine at GPU Max, others do not. This is worth noting. The more recent the coin, the more scrutiny I would give to it being immediately sold on Mt Gox if I worked in law enforcement. I would especially be watching people who are withdrawing money from MtGox that have absolutely no technical or economic background at all if I thought this was an elaborate money-laundering scheme. And yes, a laundering scheme *has* to be at least somewhat elaborate, because if it isn't, it won't be profitable.
I just want to end on a final note where I again reiterate I don't necessarily think any money laundering is being done, but if I was asked to provide "clean" coin, this is exactly how I would have developed my system.
