I never said or even implied we have no agency, but I'm also not deluded enough to think we have free choice under capitalism. We are not only literally indoctrinated from birth and essentially brainwashed our entire lives from that point in to consumerism and "keeping up with the Joneses", but we are also entirely dependant on participation in the system for survival because it is designed that way. You wanting to think you're somehow above it (even if you have learned to identify some of the propaganda and try to avoid it, which is simply impossible to do), or wanting to blame those who aren't "above it" for the system instead of those actively implementing and profiting directly from it, doesn't change that.
Freedom, and specifically freedom of choice, is capitalism's biggest con.
