Going to be honest. After the organ harvesting thing, I'm pretty close to saying we should cut trade with China, period (and if you disagree--when would you have cut trade to Nazi Germany?)

In an anarcho-capitalist universe, the idea of tariffs or cutting off trade are both impossible to enforce and incoherent.

But we don't live in that universe. So where is the line of where it is unethical to prevent a man from trading with China?

I can't simply say 'You may benefit financially, even against your will, from certain things the United States does, so ethically it can impose whatever penalties it wants on you'

But I think there is SOME line.
