Not every user of such a platform would make online black markets, but if it were designed properly it wouldn't be possible to stop anyone who wanted to.
Why DPR is in trouble is not that he designed a website, but that he personally and directly facilitated illegal black market activity, publicly promoted it under his name, making it clear that this was his intention, and directly took a commission from activity he made it very clear he knew was illegal, and was illegal on purpose.
Someone who designed a p2p system that allowed the creation of online markets and either remained mum on their intentions or, for that matter, actually had no intention but to create an anonymous online market, would have much less chance of running afoul of the law.
DPR's bust (whether or not it is legit) has done one good thing, and that is to provide an example of how not to do it. I.e. a centralized market under the control of a megalomaniacal ideologue who, moreover, directly participated in illegal activity himself and profited vastly from it.
That's fair comment, I don't see how anyone can really dispute that unless you're in the anti establishment, all else is forgiven, folk hero camp. In the final analysis whatever happens to him is largely self inflicted.
That said I do not support the false wars on some drugs and some terror, which in truth, are really about attacking what little freedom and liberty is left. All they really achieve is a tightening and extending of the power and control the structures of the state possess over everyone's life.
What we need is someone to beat them at their own game but that game is bent and that's where they have the advantage, the crooks are in charge and free thinking people need to figure out some way to get back what has been taken away from them by the banksters on wall street and their captured government puppets.
