You also have the converse problem, that a lot of value isn't transactionalised at all - if two people who look after their own children switch to paying each other to look after each other's children, GDP goes up.

So what should we be measuring? Value consumed by natural persons? That's the end goal of all economic activity, right? (But even then - if someone receives (privately purchased) medical treatment for an on-the-job industry, that would contribute to my "value consumption" measure but it shouldn't)
