Thank you for an interesting and important post. It is amazing how many well-meaning Westerners want to ban poor and desperate people from doing things that would genuinely make their lives better, simply because those Westerners cannot imagine themselves ever being so poor and desperate that they would voluntarily [work as a labourer in Qatar | work in a sweatshop | sell a kidney | insert example here].
I made a similar point in Don’t take bad options away from people but I hope that your more concrete and less abstract post will persuade people more effectively.
I disagree that this is a fully general argument and I think the phrase “a quick welfare race-to-the-bottom whereby people can be subjected to anything as long as there is something to gain” is tendentious and hostile.
I do generally support letting people take ‘bad’ options which they reflectively endorse as their least-bad choice in the imperfect world we actually live in; AlphaAndOmega has gone into depth on the specific ‘bad’ option of performing migrant labour in Qatar. I can’t speak for AlphaAndOmega, but I’m also a libertarian and have strong moral objections to stopping consenting adults making their own choices which don’t affect anyone else.
But here are some things people might be subjected to which I don’t support, and which this “fully general” argument doesn’t support:
Anything nonconsensual
Deceiving people into giving consent
Things which have large negative externalities on non-consenting third parties
Getting minors or the mentally handicapped to ‘consent’ to things they are not equipped to understand
I suspect that you are pattern-matching us against some other argument that is not quite the one we’re making. Perhaps I’ve misunderstood you—would you like to elaborate on your concerns?
