Who is behind Bitcoin and what are their declared goals?
What makes them believe governments will not be able to stop the use of Bitcoins in the developed world if Bitcoins get significant traction? Is the goal to get traction in the developed world in the hopes of converting that temporary traction into a persistent presence (on smartphones since computers are not widely deployed there) in failed states and weak states?
(If it gets significant traction, I consider some first-world government’s not wanting to shut Bitcoin down as so unlikely as to be not worth explicitly asking after.)
What government attack vectors against Bitcoin do you deem most likely to work? (There is probably a discussion thread on the Bitcoin forums on this matter.)
One obvious (and rather covert) method to undermine Bitcoin is to apply sufficient computational power before the computational power of honest users becomes prohibitive. This would permit a wealthy government to perhaps double-spend bitcoins, undermining the entire network.
An overt method would be to join, and then try to track down (via ISPs) the user associated with every public key.
Simplest attack: just make it illegal and prevent people from converting bitcoins into cash. If it isn’t connected to the larger economy not many people will be interested in it.
Why bother, when they can just use existing laws? Classify bitcoin users as banks, then fine them for violating existing transaction-reporting laws. Tax violations. I’m sure there are dozens if not hundreds of regulations that someone can be charged with.
Not reporting income or profit. Not reporting what you paid to other people that should be counted as their income, and so on. The US seems especially hostile to this sort of thing, what with the number of post-9/11 financial regulations added. I daresay they won’t be happy that anyone can just become their own bank and not fill out any paperwork at all… let alone the relative impossibility of remotely freezing someone’s account or seizing their assets, without first involving every third party they might trade with.
I expect that some clever lawyering and accountancy will be necessary to protect bitcoin users from legal harassment in the future, and that the only thing protecting them now is the relatively low-key nature of the stuff. But it’s only a matter of time until the media begin the blitz to portray Bitcoin as a tool of terrorists, druggies, black-hat hackers, gunrunners, money launderers, and whoever else will scare their viewers via guilt-by-association. Oh yeah, I forgot to mention pornographers, and by extension, human traffickers and child molesters. That’ll be enough to get political support for a crackdown, I imagine.

IANAL but I think that a court might not look kindly on an argument that turns every person who is using something into a bank. The decentralized nature undermines that argument.
As to reporting, there’s no reason in principle that bitcoin users can’t report the money they owe for taxes and the like. More of a problem if you pay an anonymous individual for some service, but that’s less of an issue if you aren’t hiring them for an extended period of time.

Unfortunately, if bitcoin ever becomes very popular, then it will be reasonable for the people who really don’t want a government eye on them to use it. Undermining authority works both ways: it might be nice for us but it can benefit those one doesn’t like also. At present, terrorists/guerrillas/freedom fighters/militants use complicated and cumbersome procedure to moving money around. Bitcoin could offer them a strong leg up. The most dangerous type of media-driven moral panics are the ones that have some element of truth.

For example, they could be using one of a dozen or so other sufficiently anonymous electronic currencies that are already available.
Pardon me, the word ‘could’ was missing, distorting my intended meaning. Edited.
I claim that the for the purposes of criminal activities the existing more popular electronic currencies are just as effective as bitcoin would be.
Now that you mention it I would claim that criminals use anonymous online currencies. Online currencies are notorious for money laundering. I have no idea what terrorists in particular currently do. Just what online resources they have available.
What government attack vectors against Bitcoin do you deem most likely to work?
From Wikipedia:
In order to prevent double-spending, the network implements some kind of a distributed time server, using the idea of chained proofs of work. Therefore, the whole history of transactions has to be stored inside the database, and in order to reduce the size of this storage, a Merkle tree is used.
So I would transact the heck out of it and make the database huge. IIRC at the moment every user needs a full copy of the database of every transaction, so if the .gov can make a multi-terabyte database a requirement, that would knock it on the head quite hard.
Also, the last time I glanced at the source code it looked quite ropey, and that makes me think it will have lots of exploitable parts lurking for the right skilled people to find and attack.
Do users need to store the Merkle tree only, or the full database? If they only need to store the Merkle tree, then could the network proportionally counteract the effect of this database lengthening by increasing the datablock length? Does use of a Merkel tree reduce the fraction of the database that each user needs to store?

If you have evidence of the existence of electronic currencies heavily and successfully used by criminals and terrorists, will you please share?
This is not actually what I claimed.
OK. What did you claim, then?
