I agree with the general sense of your post, and its implications about current drug policy, but I think tptacek is right about what our focus should be in this specific trial.

To be intellectually honest about this specific case we're discussing, DPR did by definition commit most of the drug charges. Even if you believe the only morally problematic charge is 5.b of count 1 (that the defendant hired a hitman to murder a troublesome user--I do hope you find that charge problematic!), which is certainly only alleged at this point, it is fact that the Silk Road aided and abetted drug trafficking, which is criminal in the U.S.

So while I certainly agree that people need to be entitled to a competent defense (and I am glad DPR will have competent attorneys to dispute the murder charge), emphasizing the alleged nature of a criminal conspiracy that we realistically know to be largely true doesn't seem to be the best place to focus on rights of the accused. In reality, the vast majority of people wrongfully convicted are going to be the ones who can't afford competent defense. So to me this case almost raises the opposite question from yours: if the prosecution of guilty defendants is undermined by their being able to afford better attorneys than the government, and if the defense of wrongfully accused defendants is undermined by their inability to afford competent defense, then we've got bigger problems with the nature of criminal trials!
