I've tried to create a steelman argument for why voluntary trade is exploitative, and I just can't come up with anything good. Every example I've seen cited crumbles under examination.
More accurate to say whales have more pricing power, but that power is not without cost in terms of liquidity and risk. I don't think it is accurate to say pricing power = violence.
I think it's naive to believe that whales haven't committed violence to hold their positions. It might even be that most violence is just whales trying to sway markets.
I see where you are going with this: there are different degrees of "voluntary." I still respectfully disagree. Better to use hard principles than try to tease out a spectrum.
