Capitalism defines labor as only having the value someone is willing to pay for it. That's how the free market works. So claiming that Captialism is somehow not internally consistent doesn't work.
Labor isn't free, it never is, and it is almost always paid for, as is law in the vast majority of cases across all first world countries.
Nature isn't free or un-free, it simply is.
And social reproduction is a stupid post-modern interpretation of human behavior. It's entire premise is based on the idea that men and women are somehow in eternal competition with one another to extract labor from one another when that's not how functioning humans view things or act on them. Life in the nuclear unit is a collaboration, not an extraction scheme.
This entire post is a really bad attempt at making Capitalists look stupid.
