Yes it is telling. It is "telling" you that I don't agree with your assertions, and I likewise regarded the rest of your message as not worthy of consideration. I am long accustomed to Libertarian types giving me their "Chicken Little" routine, and I have long grown tired of hearing them screech about how the "Sky is falling" just because we keep very dangerous and addictive substances illegal. (Though we have done so for over 100 years.)
I doubt most libertarians have given any serious thought as to what happened in China, and I likewise doubt they can come up with any reasonable argument as to why a similar disaster would not happen here if we were so foolish as to do what the Chinese did. (Legalize drugs.)
I would suggest you not bring up the topic of "unintended consequences" until after you've come up with an explanation as to how the "unintended consequences" we would face in this nation will not resemble the "unintended consequences" which the Chinese faced after they had legal drugs for so many years. As near as I can tell, legalizing drugs is tantamount to a nation putting a gun to it's head and pulling the trigger. Except that it happens slowly.
There is no enumerated power for the federal government to conduct the domestic "war on drugs". You claim they use the Commerce Clause because they're too lazy to use Defense, but all that does is excuse you for being too lazy to be bothered with getting the amendment we need to enumerate the power, and do it the way it was intended.
