That said, I do think he absolutely deserved to be released, not because he didn't deserve to be locked up in the first place, but because he's clearly been rehabilitated and has done great work during his time in prison. All that considered, ten years seems like a not unreasonable prison sentence for what he did. I hope he'll continue to do good when he's released.
The guy operated a marketplace for illegal goods in order to enrich himself. The illegality wasn't just incidental, it was literally his business model -- by flouting the law, he enjoyed massive market benefit (minimal competition, lack of regulation, high margins etc) by exploiting the arbitrage that the rest of us follow the rules.
Said a different way, he knowingly pursued enormous risk in order to achieve outsized benefits, and ultimately his bet blew up on him -- we shouldn't have bailed him out.
The idea that possession of drugs is or should be illegal is purely arbitrary, and is used thus to justify massive violations of human rights. It is literally insane that the state claims authority over what you are allowed to do to your own body.
No victim, no crime.
I'm not arguing that drugs should be legal, but we do have to be clear that the reasons for banning them and the punishment are not necessarily rational.
