"Government" is not just cooperation and/or organization; it is violent domination. The only difference between voluntaryism and statism is that voluntaryists don't pretend that "authority" is real, or that anyone has an exemption from morality. There are literally millions of ways to organize and work together on a VOLUNTARY basis. What is "egregiously wrong" is the notion that violently dominating people is okay if it's called "law" and done in the name of the "common good." In fact, that has been the cause of the vast majority of injustice and human suffering in history.
