Don't forget that pure democracy is a form of collectivism -- it readily sacrifices individual rights to majority wishes. Since it involves no constitutional bill of rights, or at least, no working and effective one, the majority-of-the-moment can and does vote away the rights of the minority-of-the-moment, even of a single individual. This has been called 'mob rule,' the 'tyranny of the majority' and many other pejorative names. It is one of the greatest threats to liberty, the reason why America's founding fathers wrote so much so disparagingly of pure democracy.
Take a look at how the multi-billion dollar pharmaceutical companies have totally snookered the politically-correct media and liberal establishments into fighting a 'War on Smoking' for them. After all, absolutely none of their anxiety drugs can quell anxiety or panic attacks anywhere near as cheaply, quickly or thoroughly as a cigarette can.
