Continuing down that logical path, it's impossible to have a truly consensual business transaction of any sort because the involvement of currency makes it coercive.
I think the implied part of this discussion is "captive". The person must at least feel that there is no other choice.
We see that in prostitution, in illegal immigrants working in horrible conditions, Dubai laborers[1], etc. In contrast, a Software Developer in the Bay area can hardly claim such conditions.
I think the implied part of this discussion is that there are transactions taking place with a power imbalance between the parties. If that is not acceptable, most of capitalism will promptly fall apart.
While I tend to agree that many (though not necessarily all) transactions exhibit a power imbalance, I disagree strongly that it's currency (or money, or other forms of exchange) which make it so.
Though if you'd care to expand, I'd be interested in your argument.
