Somehow I think you missed the whole "Every transaction is public" part of Bitcoin.

Cash is difficult but not impossible to track, Bitcoin is ridiculously easy to track by comparison.

Except that Bitcoin can be laundered quite effectively, and often is. [1] In fact, there are services that do so. [2]

Try and launder a 1Billion to 10 Billion dollor transaction with bitcoin and that's going to fall flat.

PS: For comparison you can fedex ~170,000$ worth of gold in a vary inconspicious 15 LB box. Shipping ~60,000 lb of gold (1Billion$) is much easier to track and more risky.

There is no possible way to make gold inconspicuous. The density simply prohibits it: gold reflects easy-to-send parts of the EM spectrum that most anything else will pass.

Your assuming there is a test in place to detect gold in FedEx packages. That's not acutally a hard thing to test and I would be interested in the results.

That doesn't mean it's ridiculously easy to attach a transaction to a specific person. If it were, sites like Silk Road would never even exist.
