resources of the State to eliminate this software are quickly and thoroughly as possible
Love the tunnel view and prepotency! What "State"? US? They rather let it fall quietly or if they go on open war on Bitcoin and make it State business tomorrow Bitcoin will be the currency of Venezuela and Russia, China and other US-less-friendly States will back it up.
There's NOTHING "the States" can do about Bitcoin, if I wasn't to believe those senators to be technologically handicapped, I would say they were consuming too much at Silk Road.
Gosh! Americans are often so self-centered that forget the World isn't USA and here you find people from all over the globe, nodes are all over the globe. There's nothing US can do about it.
EDIT: If US want to challenge Bitcoin they can create e-Dollars, signed cryptocurrency backed by USD that is as good as Dollars. Obviously such currency would never be actually need to be exchanged to fiat as it would be fiat itself, but by being Dollars they would put btc out of commission in no time... except that Silk Road users would find it even better to use, so to that end it would make things worse.
As always, technology is changing the World.
