> Some of us see a major difference between selling heroin to someone, and building the marketplace from which these victim's freely bought drugs.

I kinda do see your point, but I think I reach the opposite conclusion. If you are one person on a street corner it's one thing, if you enable a whole electronic marketplace you have a much larger effect.

Then again we should decide whether it's a bad thing to sell drugs, but if it is I would see him as more culpable than a random street dealer.
