Sure, but that argument is specious as hell, right?
Like, if everyone in the United States decided to give you a $5 bill, does that instantly make you a bad person who exploited labor to get where you are?
"There is no ethical consumption under capitalism" is simply a rhetorical device to outline the flaws in the system. It completely breaks down when used as justification to villainize someone.
Your position could be equally stated as, "anyone who has more money than me is a worse person than me, and anyone with less money than me is a better person than me." It's a misuse of the "no ethical consumption" idea on its face.
