It's a powerful signal containing important information! You don't have to go along with it, but it may be beneficial to others if you do.
As an example, we bought a new car in 2019. We were planning to sell our old car but every time we were about to sell it, it came in handy - family came to town and we needed two cars, or it was nice to be able to go two places at once.
In 2020, prices shot up. Suddenly, it was worth it to sell the car.
Someone who valued it more than us got to use the vehicle. Was that greed?
