I think people should able to do drugs without fear of punishment, and said so in the column above. Anarchy is more about getting rid of taxes. Not just high taxes, any taxes.
But in your made up world you are just renaming and reasigning responsibilties. Instead of taxes we have insurance. Instead of gov't we have agencies. If you follow the natural course you will be right back where you started. I can't imagine you can't see that. I think the desire to make drugs legal is clouding an otherwise rational mind.
