Don't you still work for time? If you have achieved something, you can do it again or something similar you might enjoy. Unless what you are doing is completely directionless and you are basically just randomly soldering stuff together, I would say there is still esentially the same loss function as with money.
I give you that the abstraction often makes you feel less pressure in the moment itself. But in the end it is really just an abstraction. Money is just a virtually constructed number we use to control people's time.
