> Bitcoin requires middleman, just like credit card processors
No it doesn't? Your address exists as a private key, no external middlemen play a part in the maintenance of that unless you want them to.
> It also is significantly easier to trace than current financial systems
No it isn't. Even if you're talking the base bitcoin without extensions like zerocoin, it is still effectively as hard to trace as it is to decrypt a widely distributed shared encrypted wikileaks file, for example. If someone slips up and a key becomes available to allow decryption, it can be done, otherwise no dice. Compare with OP's statements about full visibility into 100% of SWIFT transfers.
And if you add coming enhancements like Zerocoin? No, it's just nowhere near as easy letalone significantly easier.
> which don't assign digital fingerprints to units of currency
Serial numbers are quite common on physical fiat currency. Electronic transfers are done via SWIFT or interbank transfer networks which have the aforementioned 100% visibility.
> that they've formed an internal task force to see what they can do about spurring adoption of Bitcoin or other similar digital currencies.
The church was one of the foremost patrons of science at its peak, that they didn't understand the final implications of those developments would prove fatal to their foundations doesn't change that fact. So it is with states and bitcoin, although from what I've seen, and I look very closely indeed, the sentiment from the state has primarily been fear and trepidation. And they are right to fear, it could and hopefully will kill them.
