Well, I guess we just disagree on the definition of rent-seeking. Matching willing buyers and sellers creates value by increasing the satisfaction of both the buyer and the seller since both should be better off after the transaction. The facilitator who creates more mutually beneficial trades is increasing the wellbeing of society as a whole. From wikipedia "Rent-seeking behavior is distinguished in theory from profit-seeking behavior, in which entities seek to extract value by engaging in mutually beneficial transactions." SilkRoad is not rent seeking because they are not looking to change or increase the transaction friction and regulatory control of the drug trade for their own benefit. That is why rent-seeking is usually used to describe entities trying to create a government policy which benefits them but hinders mutual exchange of others. To define rent-seeking is such a loose way as to cover all facilitators who don't produce anything directly is to distort it's original meaning and make the word useless to describe true rent-seeking.

Who is creating the majority of friction in the drug trade? Nation states and their war on drugs.

Silk Road is using technological advancement to remove as much friction from the process as possible, but it's obviously still non-zero, just like any market in the world.

Do you have any points to offer other than useless snark? You have multiple comments challenging your initial claim that Silk Road is rent-seeking and you have yet to offer any sort of defense of your position.
