What exactly is your criticism here? That he was an ideological crusader? Because so was Satoshi. That he was a drug dealer? Fair enough; some people find that distasteful. That he was an an-cap? Well, so is probably 20% of the community here. That he claimed to be a libertarian but did some unlibertarian things like buying a hitman's services, selling forged documents, etc? Hey, that's something most people can agree on.
Of course drug dealers don't want drugs legalized. DPR claimed he wasn't just a simple dealer but rather some ideological crusader for a better tomorrow (by which he meant: anarcho-capitalism, his idea of utopia). He wasn't only selling drugs remember, but also malware, forged documents, he experimented with selling weaponry, etc ...
