I wouldn't be so sure of that, if you are in USA getting drugs via mail its automatically a federal crime and you would very likely get at least a few years in prison if you had any amount of schedule one drugs intercepted, although you would probably have your case given to state and do most time on parole. In some states you can probably get very fucked for getting drugs in mail even as compared to federal. Plus you are probably also chargable for federal money laundering which could get you twenty years in prison if they really wanted to fuck you. You probably break a number of other laws also, every time you get drugs in mail pay for them participate in a network that trafficks them (you can probably be charged under RICO for participating in a drug trafficking organization and get a life sentence if they really want to fuck you....SR is probably the largest drug trafficking network that has a formalized name that I have ever heard of but it is still a drug trafficking network and a DTO in the eyes of the DEA. Silk Road is a more modern sort of drug trafficking network, this sort of network and the techniques we use were actually first mentioned in a paper by a US military think tank, it is titled Netwar: the future of crime terrorism and militancy , and discusses concepts such as product swarming (massive network with individual nodes moving small amounts, breaking large amounts up into smaller packets etc) encrypted communication, network overlays etc. although a lodging of wayfaring men is a nice cypherpunk fiction book that also describes things it might be more appropriate for the SR audience than a serious research paper
