Anarchist Capitalism is a delusion. You're always going to have someone with a bigger gun telling other people what to do. That's a de facto state whether Peter Thiel and Murray Rothbard want to admit it or not.

Once you sever democratic control of capital and allow landlords the freedom to raise rents, the ball only continues to roll downhill. People will keep looking for chinks in the regulatory armor (or create them through brute force) until the market system collapses. There is no "regulated capitalism" that endures continuous contact with the corruptive influence of the profit motive.
