Normally, when you challenge the conventional wisdom — that the current economic and political system is the only possible one — the first reaction you are likely to get is a demand for a detailed architectural blueprint of how an alternative system would work, down to the nature of its financial instruments, energy supplies, and policies of sewer maintenance. Next, you are likely to be asked for a detailed program of how this system will be brought into existence. Historically, this is ridiculous. When has social change ever happened according to someone's blueprint?

—David Graeber
