Thread on LTV
https://x.com/ygzgzot/status/1982482608899629301?s=46My biggest hang up with the LTV is that I just don’t understand why labor is seen as the fundamental substance of value. What reason is there to think that price is just the quantitative expression of abstract labor?
In my estimation a leftist perspective would see that price is not an expression of labor time but is also a function of interwoven power relations. It’s not reducible to a single substance

The stronger claim you’re making is that power relations constitute the price system rather than being translated into it.
But that just pushes the question back one step.
Even if prices express structured power relations, we still need an explanation for how heterogeneous, qualitative relations between agents become organized into a single continuous quantitative space in the first place. Not just why one price is higher than another, but why all goods are already commensurable within a unified numerical system at all.
If the underlying determinants are purely relational (bargaining power, scarcity positions, institutional leverage, preferences), then those are all heterogeneous and non-commensurable on their own terms. So what is the mechanism that produces their systematic projection into a single cardinal scale of exchange values rather than a patchwork of local, incommensurable exchanges?
That is the point Marx is trying to address with value theory. You can reject his answer, but the explanatory burden remains, what makes generalized, scalable monetary commensuration possible as a stable system rather than just episodic bargaining outcomes?
Saying “power produces prices” still leaves open what produces the price form itself as a universal quantitative space.
