Ross Ulbricht was arrested on 1 October, suspected of being the Dread Pirate Roberts, the mastermind behind the online illegal drug emporium Silk Road. Messages of support quickly spread across social media; funds are being raised for his legal defence. The Silk Road was shut down on 2 October. Allegedly run out of Ulbricht’s bedroom in a shared flat in San Francisco, the website boasted more than 950,000 registered users, and made getting drugs – apparently very good drugs – much easier and safer than ever before. But its founder isn’t a folk hero only because of the quality of the junk he made available. It’s also because of his radical libertarian philosophy.
