Soo.... hold on now. The activities of the Silk Road were so nefarious that they just had to get shut down. We can't have evil people giving money to some DPR kid. But hey, it's fine if the government profits off of those same nefarious acts? So it's wrong for people to profit off of illegal drugs, but perfectly fine for the government to now profit off of it?
If they really want to set an example, I say they should destroy the coins.
