This would mean, of course, that humans can be money-pumped. In other words, if this is really true, there is a lot of money out there "on the table" for anyone to grab by simply money-pumping arbitrary humans. But in real life, if you went and tried to money-pump people, you would not get very far. But I accept a weaker form of what you are saying, that in the normal course of events when people are not consciously thinking about it we can exhibit circular reasoning. But in a situation where we actually are sitting down and thinking and calculating about it, we are capable of “resolving” those apparently circular preferences.

No, not "of course". It only implies that if they're rational actors, which of course they are not. They are deal-averse and if they see you trying to pump them around in a circle they will take their ball and go home.

You can still profit by doing one step of the money pump, and people do. Lots of research goes into exploiting people's circular preferences on things like supermarket displays.

I think you are taking my point as something stronger than what I said. As you pointed out, with humans you can often money pump them once, but not more than that. So it can not truly be said that that preference is fully circular. It is something weaker, and perhaps you could call it a semi-circular preference. My point was that the thing that humans exhibit is not a “circular preference” in the fullest technical sense of the term.

Well...
