We, the bitcoin users, don't need the bitcoin foundation to represent us. We have no faces. If any user, US government included, has any problem using Bitcoin, we can help him in the bitcointalk forum. But nearly all the questions a government could have about Bitcoin are very well explained in satoshi's paper and the source code. The only words the foundation had to say in that meeting: read the paper and the code as all of we did, it's all explained there.
Senator Ted Stevens of Alaska described the internet as "a series of tubes"... in 2006! What makes you think any government is going to read source code to understand a technology?
It's time to pull our collective heads out of the ground and recognize that
doing nothing is the worst possible approach. If we (as a community) don't communicate with US government officials, Bitcoin will remain over-regulated, preventing legitimate businesses from springing up.
You can want "no regulation" as much as you want, but it's not going to happen with Bitcoin any time soon. Accept it.
