My perspective is that you can do what you like with yourself and your life, up to the point where it infringes on my right to do what I like with myself and my life. That means you can't steal my stuff or injure me, or keep me from legitimately enjoying my stuff on my own property. It doesn't mean I can play my obscene and obnoxious music so loudly that you can't listen to your own obscene and obnoxious music in peace. If I want to have oral or anal sex, as long as it is with a consensting adult, why should that be illegal? Drugs? Legalise it all, but have big penalties for doing any harm or damage to anyone in the process.
This is not anarchy, it's libertarianism.
