Welcome to the other side!
I've been a self-proclaimed anarchist for around 5 years or so. Before that I considered myself a Libertarian. Before that a conservative. And before that, I was just too young to know anything about how the world really works, but I did a stint as what I would categorize today as a Marxist communist.
What still amazes me is that when I explain the philosophy of what you call voluntaryism and what I call anarcho-capitalism, to a statist, how often they agree with everything I'm saying, right up until we get to a topic that they don't agree with me on.
For example, drug use. A "conservative" statist will agree with me that I am a sovereign individual, and that nobody has a right to take my property. But as soon as I say that I'm in favor of eliminating laws restricting all types of narcotics manufacture, distribution, and use, they start to tell me that drugs are a danger to society and that they need to be regulated.
What I've determined is that all statists are basically just statists.. It doesn't matter if they're liberals (excuse me, progressives) or conservatives. They're still statists. And they fundamentally believe that they have authority over me -- even if they tell me they are protecting my freedom.
