The GDP model is inherently broken.
This is just an extension of a fundamental flaw in GDP: A beautiful, old growth tree provides so many blessings: shade; oxygen, beauty, maybe fruits, etc. etc.
Contribution to GDP: $0.
Chop it down, mill it with horrible chemicals, print up a stack of porno mags.
Contribution to GDP: $1,000.
There are many wonderful 'free' things in the world. Home grown food, community cooperative improvements, the value of raising children, coming together with old friends and a guitar.
The GDP of all of them: $0.
We should simply stop thinking in terms of GDP, it's an inherently broken metric.
