I have a much more positive view of left-libertarianism, but I also always enjoy Alex Strekal's criticism.
On the origin of the word 'capitalist'
Sheldon Richman got an introduction to the libertarian left and free-market anti-capitalism published on The American Conservative back in 2011.
“And your old buddy Ronald Reagan! Now there’s a lesson in liberty for you. On one side of People’s Park there is the State of California with its right of eminent domain. It took the land. I would say it stole the land. How, I wonder, do you describe the right of eminent domain? On the other side are people who have an exotic notion about ownership. They don’t think it should be exercised at the point of a gun or a bayonet. They worked that land. They homesteaded it. They owned it in a sense far deeper than any government proclamation. Think of it that way: a scrap of government paper on one side; real people on the other, and your old friend Ronald Reagan, so help us, now supporting that scrap of paper against the people, with as much bloodcurdling diligence as any man you ever fought in the political arena. Senator, are you really sure you want to be a deputy sheriff for state power? That’s just what you are on the other side of the fence at the People’s Park!”
