Not all value add is compensated, that's the concept of positive externality, and it's a market failure.

If we want to get really precise, we can say that people give other people money for any number of subjective reasons, but the large majority of the time it's because the person wants something from the other party that the other party isn't willing to do without compensation. So money most of the time represents subjective value add that wouldn't otherwise have occurred without it. Cleaning services, manufacturing, specific engineering work, construction, etc.
