The majority of personal use sales are not conducted with a "gangster", true, but the small-time college ecstasy or coke dealer conducting those personal use sales IS making regular trips to the hood, purchasing from people who are hardened criminals. They expose themselves to a lot of risk in doing this.

You don't have to move far up the chain before you see some serious violence. Personal use weed dealer? Probably not going to get killed. But robbed? Yes, definitely, seen it happen many times. Personal use coke, ecstasy, heroin dealer? Much more likely to experience violence. The dealer one level above, supplying the personal use dealers? They get killed all the time, despite not being drug kingpins in any sense. It only costs 1000$-2000$ to have someone killed in many parts of the US, so that should say something about the chance of violence that small-time dealers face.

Silk Road was more than personal use sales, I'd bet the majority of its revenue came from pounds and half pounds of weed, sheets of LSD, and orders of 500+ ecstasy pills. Heroin and coke haven't caught on as much yet in the online scene, with prices still a little above what well-connected users can get on the streets, but give it time. Also keep in mind that the online drug scene is more than just SR/BMR/Sheep and that there are private forums that deal strictly in wholesale.
