Studio, not all left-libs believe in the LTV. The founder of the philosophy, Sam Konkin, did not, nor does Roderick Long or Brad Spangler. All of those people are entirely Austrian in economic theory. Even Kevin Carson incorporates subjective aspects in his interpretation of the LTV. However, left-libertarians usually do use a negative definition of capitalism. I know I have. However, no left-libertarian wants to stop "exploitation" through force. SJW, you're generalizing wildly. Roderick Long considers himself an Aristotelean and has spoken positively of Rand in the past, and the founder of the left-libertarian forums follows Aristotelean virtue ethics.
