You're still comingling the concepts of capitalism and markets. I actually 100% agree with your entire post (as a description, anyway, not as an ideal or with respect to the conceptual foundations of property rights), but is in no way a refutation of what I said or what Marx said. It's somewhat tangential entirely, really.

EDIT: Also, I wouldn't use the word "exploit" in such a simple descriptor of commerce.
