I think you are over-analyzing with unreasonable assumptions: “Let’s say the person has some superstition against cash, and does not feel good receiving the $100.”
- Try sticking to reasonable assumptions. Don’t make things more complicated.
- We are trying to understand Buddha’s teachings to remove future suffering. You seem more focused on making “lawyer-type” arguments to see whether Buddha Dhamma is “logical enough.”
- That type of approach may not be conducive to learning. Furthermore, I don’t have the time to analyze all kinds of hypotheticals.
The best approach is to analyze your own scenarios/experiences rather than try to come up with far-fetched hypotheticals. If you do that, I would be happy to help.
