No.
Commodity fetishism is the observation that through many small separate acts of market exchange we command each other to behave in very specific ways, while disclaiming this same power and attributing its commands to blind necessity. It’s a key concept in Marx’s critique of capitalism (he devotes a whole section to it in Capital), and Marxists should understand that Marx used the term “fetish” to argue “commodities behave like little gods in that they seem to command men” and not “consumerism is immoral and vulgar." [...] We should endeavor to correct this misunderstanding, since the alternative interpretation transfigures Marxism into a monastic doctrine of pious asceticism that — putting aside any of its moral merits — is very unappealing. Marx was very confident that such a project would never grip the masses and lead them to struggle and triumph over capitalism.
Very interesting.
