But if this is already true by default, then we're back to square one where the important financial decision was already made. Again, if it was already decided by default that there is no sale to be made, then whatever the end user does after that is irrelevant.

But beside that, in my last response I gave you three very common reasons that people do buy things against their own financial interests, and you've ignored that part. How do you fit that into your argument?
