While there are certainly problematic aspects of dark web markets, society do get some benefits. No physical contact between sellers and buyers, which reduces violence. Reviews of sellers and products makes it significantly easier to purchase safer drugs (for some drugs, adulterants and/or unpredictable potency are a bigger risk than the drug itself). This translates to fewer visits to the ER or morgue.
Edit: My personal opinion is that we should rid ourselves of the demand for dark web markets by regulating drugs. The regulations should focus on harm reduction, both for the users and society as a whole.
