I'm not saying licensure is compatible with libertarianism. I'm saying I never advocated for the elimination of all licensing, so you were attacking a some imaginary libertarian strawman, not replying to me.
Uh, care to share where you read that? What I read was:
"Almost nobody is calling for wholesale abolition of professional licensing. I sleep better at night knowing that the commercial pilots flying over my apartment are trained and licensed."
"A bolder idea, of course, would be for states to get rid of the licensing rules that are doing more harm than good." (emphasis mine)
