“The war on drugs is a costly game of cops and robbers. One illicit business is shut down, and a dozen more spring up. Instead of chasing after the administrators of online marketplaces, the authorities should check out the business model with a view to drug decriminalization. A rating system for buyers and sellers, similar to that operating on eBay, and the sterile, anonymous way in which goods and money change hands, would serve nicely to bring down street crime and the use of contaminated substances. It is a fact of life that these substances are readily available anyway, only without any kind of quality assurance system and often in dangerous settings.”
