I would not want people to money-pump me from my delusions, even if it were profitable to them, and even if it were a very bad delusion.
If people have highly money-pumpable delusions that they can be money-pumped in a completely honest and open fashion then the individual is likely so irrational that the resources will be much better used when transferred to the one doing the pumping.
I'm confused. I thought "pump" was a word used in dutch-book type arguments, where (to continue the analogy) the guy wanted to sell swords for less than he wanted to buy them for.
That is a different ethical situation, because at the end of the day you end up with both the swords and the money.
This is how I had understood "pump" in this general context.

Having thought it over, I'm OK with the ethics of this service.
