Exactly, free will over the actions you take proves self-ownership. The problem, I find, is convincing someone that using force to exert your will over another person should be abstained from. People have been so thoroughly indoctrinated by state education that they believe it a necessary evil. I guess that's why I enjoy Rothbard, like you said, he does explicitly lay this problem at the feet of government. Rightfully so, I think. I believe what he calls for in many of his writings is not a political shift but a ethical shift. That even the best government we could envision when given a clean slate in 1776 in the United States still uses coercion to enforce its policies and is inherently immoral when examined through the lens of ethics. That government along with all other coercive institutions should be abolished.
