I think the quote that pushed it over the edge for many is: "THE DREAD PIRATE ROBERTS isn’t shy about naming Silk Road’s active ingredient: The cryptographic digital currency known as Bitcoin. “We’ve won the State’s War on Drugs because of Bitcoin,” he writes."
There is one fantastic side benefit that go's unnoticed. The fact that drug lords have to compete on quality and a positive reputation as they can't use brute force and violence to monopolise a street corner or a territory.
DPR should have said: “We’ve won the State’s War on Drugs, by usurping violence and disarming drug cartels because of Bitcoin"
I would agree with you, if SR's sibling site didn't sell guns.
Note that it was taken down but DPR said he wants to bring it back if it's profitable.
