The simple fact is that the majority of citizens don't want online drug dealing to be legal, so it isn't legal.
Last I saw, several US states were legalising marijuana sales. It seems that attitudes are shifting.
Your statement is also simplistic: a majority of citizens don't care one way or the other about catching undersized lobsters, yet it's illegal. Trademark infringement is another such law. Then there are laws that the public kind've want but the people in power don't, so they don't get made (eg protection for whistleblowers). The simplest counterexample is tax law. Taxes are incredibly unpopular, yet laws requiring taxes exist.
The genesis of laws is a lot more complex than magically popping in and out of existence with popular demand.
