This kind of stupidity is baked into human thinking.

People that want liberty will always be a minority ( as we see in now with the amount of people voting for the corrupt and venal Clinton))

Daniel Okrent wrote an excellent book on prohibition, *Last Call: the Rise and Fall of Prohibition* detailing the various social movements pushing for Prohibition,  Unsurprisingly, FDR sitting in his den sipping martinis  while directing the Bureau of Prohibition was a symbol of the Northeastern progressives who led an influential, but largely unrecognized component of the movements.  It wuld have been a perfect book (well researched and organized), bur Okrent keeps making excuses for the Progressives while admitting the harm they did.

There are two great hindrances to effective governance:  do-gooding and rent-seeking.  The combination of these motives is known as "Baptists and Bootleggers"

Prohibition and the "War on Drugs" are simply the symptoms of human stupidity.  I can guarantee you that a program (not a government run program, but a social movement) designed to shape humans into logical and responsible actors would not just be opposed by the do-gooders and the rent-seekers, but by the people themselves who do not want to be held responsible for their own actions.
