I like this thinking about other people's time as opportunity cost. I do that a lot and always encourage others to keep it in mind, too.

An example: a few years ago, there was a recurring unnecessary traffic congestion on my commute because of a malfunctioning traffic light. On the third day, I did some numbers while waiting and came to the conclusion that over hundreds of people, this was quickly adding up to months of lifetime wasted in total.

I then called the responsible municipality right on the spot to notify them there's a problem. They thanked me and had it fixed the next day.
