War against drugs kills people everyday and destroys whole societies. It's way worse than what online marketplaces are doing. In the future, all individuals supporting war against drugs are considered as evil as nazis who supported war against jews.
And besides drugs, most of the things and services sold are not real, they are just scams.
Those drugs on marketplaces like Alphabay are sold by terrorists and mafia to raise funds so they can keep chopping heads off and leaving bodies everywhere, not your friendly neighborhood weed dealer.
