I was thinking the same. The fact is people want to do business with each other, it's been normal activity since we started doing this kind of thing.
The government saying we can't unless we play by their (pain in the ass) rules means nothing if there is an alternative.
Yes bitcoin is probably going to be illegal, but if everyone's doing it, and very few, if any are caught then it doesn't matter. We don't have to deal with the government anymore if we don't want to.
"caught"?? Come on.. I highly doubt the government would start penalizing citizens for using something that was advertised/widespread in the least.
It's not like they started arresting people who tried to use liberty dollars. They only arrested the founder.
