I agree that in small situations you can bring social pressure to solve this problem. Sometimes. Some families break up over issues like this.

As you scale up, it gets harder and harder. You get a few people who are intentional free riders. The hard workers see the free riders sitting right next to them stop. Then more and more hard workers defect.

That system of emergency operations is a great counter example. You correctly point out that it's good to have a system with more than just monetary incentives. You have to have a mix of monetary incentives, punishments and other incentives such as just the feeling that you're helping out, or perhaps prestige.

I'm not arguing to get rid of all incentives except money. Those other levers are vital. I'm arguing against a system with no money.
