However, I think you are trivializing it. The fact that some people do something that is illegal doesn't mean that the law has no effect. Alcohol is practically the only recreational drug I use and the same applies to a large group of my friends. I am sure that if other categories had been legal, they would have been more common as well. My parents would have had a harder time convincing me not to take something if you could buy it in a safe location with knowledge that the production was controlled etc. Now I'm not necessarily saying that this would have been worse, but you're suggesting that the only thing that would happen from legalizing everything would be that people would keep consuming like they do today (because people who want something can get it anyway), and drug lords would be replaced by taxable corporations. Which I think is hardly the case.
