You pointed out an interesting problem, but I still think that if someone engages in a voluntary transaction, they have to anticipate that it will be beneficial for them. They may anticipate it for the wrong reasons (meaning that they will not be satisfied ex post) and PSYOP may play a big role here, but I think it's still a special case of an error of judgment, because, after all, it's their decision and their anticipation.
