The only problem with silk road is it's only going to take one police officer who creates a fake account and pretends to sell something to ruin the whole thing.
Think about that for just a minute okay? First of all, that
might be entraptment. Second of all, the only thing said police officer can do is arrest someone in their OWN jurisdiction. Feds? DEA? Not Profitable. DEA/Feds are little more than an extortion racket. There's no profit to be made here unless the attempt is to undermine public confidence in anonymous transactions through a
handful of publicized busts. Doing things the way you suggest LE might has several problems.
1. Not enough resources to arrest all users.
2. Arresting all users would dry up demand for their thuggery market.
3. Nothing to extort from anonymous buyers. Sure you give them your address but who are you going to snitch on for them? Anyone else you bought from on SR is
anonymous.
Biggest threat toward buying anonymously is ripoffs. Accounts with higher rep will be able to sell a higher price for those wanting less risk for larger purchases. Newer sellers will sell cheaper, smaller quantities to gain rep etc. This system really could work to overgrow the fascist thuggery & its systematic lies & abuse.
