That site doesn't address on HOW they're going to take SilkRoad down. They were only able to take FreedomHosting down because it was in a centralized location. Silkroad's server is changed at least once a month and is not a part of a single Tor hosting package. It's the third most protected Tor site, OP's site only has someone who is paranoid because some jackass allowed CP tied to his hosting company.
Bitcoin won't go anywhere because it is not centralized as well.
