Yes, I read that post. I think that looking wider than the Silk Road angle reveals an even bigger prize: Bitmit ended somewhat ignominiously. The ownership of that site was a bit of a hot potato, and it perhaps ended up in not the best hands.
But what they were aiming at was so valuable: selling highly valuable items for BTC. eBay need all sorts of permissions about what they can or can't sell, depending on the jurisdiction. Some governments just want their buddies in "accredited" institutions to have a cut of the action. Given this, uncensorable sales listings are perhaps even more laudable for houses/property, cars, yachts, businesses etc than they are for contraband. Combine it with the smart property and contracts stuff (enabled in a separate channel of the same model, of course), and all of the "the law is there to protect your rights" stuff goes away too. Sales agents, legal draftsmen, ownership transferral authorities, they can all wave goodbye, and try to find someone else's lunchtable to vacuum up the scraps from. Government stands watching, jaw moving, but no words.
