“I think we were past that point [of banning Bitcoin in the US] very early on because you’d have to shut down the internet,” Peirce said. “I don’t see how you could ban it. You could certainly make the effort. It would be very hard to stop people from doing it [trading Bitcoin],” she said. “So I think it would be a foolish thing for the government to try to do that.”
Though, as Peirce said, in reality this would be very difficult: technology will likely outpace the government’s attempts to limit Bitcoin use, since people will always be able to download Bitcoin wallet software, run a node, and make transactions as long as they have access to the internet. What may be more likely, in the short to medium term, are clearer Bitcoin regulations.
