Well I guess you could also say prohibition began with the invention of liquor, but that would also be stupid. Prohibition was put in place by Evangelical Conservatives who believed drinking was immoral. The War on Drugs was the baby of noted lib Richard Nixon and was greatly expanded under his Democrappy butt-buddy Ronald Reagan.
Nice partisan talking points, but you are completely ignorant of history.

Prohibition was undeniably the brainchild of the Progressive movement; this is basic stuff that's taught in every history class. Why do you think we have an income tax now? It's because the liquor excise tax was funding much of the government before then, and the Progressives realized that would have to be addressed in advance before banning liquor. Even the 17th Amendment partially fed into Prohibition because the state legislatures who previously elected senators were doing lots of backroom dealings in saloons. And of course, the Wartime Prohibition Act was passed before the ratification of the 18th Amendment. All of those societal changes added up and slowly desensitized people into accepting a full-out liquor ban.

Likewise, the War on Drugs greatly predates Reagan. In fact, it was known lib Woodrow Wilson, not Reagan, who signed the first federal drug regulation, the Harrison Narcotics Tax Act of 1914. Marijuana started being taxed in 1937 under known lib FDR. Mandatory sentencing was introduced with lib Truman in office via the Boggs Act of 1951. Believe it or not, Nixon, who was as anti-drug as it gets, actually repealed some of those mandatory minimums.

Of course, the "death by a thousand papercuts" approach only delays the inevitable: the rise of the black market and cartels. We saw it with alcohol, we're seeing it with drugs, and there's no reason to believe that a gun ban would be any different.
