Earlier quoted context omitted.
We have to ask ourselves what we want. Because it's not GDP, you can't eat GDP or sleep under it, you can't even withdraw it from the bank. So more directly, how does it influence our life? (Of course GDP influences our life to some extent.)
Take pretty much any quality of life thing. Just as one example Mississippi: The average home size 2,065 square feet United Kingdom: The average home size is 818 square feet No, you cannot "eat GDP", but its a useful proxy as it correlates very highly to a lot of things we do care about
Mississipi: 24.5/km2
UK: 279/km2
Maybe, only maybe, that has an effect on house sizes?
