LR was a centralized target. Shutting Bitcoin down will be like playing whack a mole. They might shut down an exchanger here or there, and then new ones will pop up. But the actual currency will not be shut down, and it is consistent across any new exchangers. LR getting shut down means that the money in LR is gone in a poof, a Bitcoin exchanger being shut down means that it is time for another one to pop up.
