Yeah but there is no actual value generated by passing the banana through the population. It's fictional growth, backed by nothing, the same sort of swindle that shitcoin creators do to pump up their shitcoin's value ("wash trading").

There will be no broad prosperity for all from that banana trading, all it serves is to further pump the inflatable house, and it will eventually pop and leave people to realize they've been conned by "financial engineers". And then, the pitchforks will come out.

I agree. And if landlords decide to hike rents by 10% this year and people pay it, the GDP contribution from rent rises 10% despite the actual quality of the housing stock being worse due to being a year older. So you can see why GDP is a kind of silly metric of productivity or well-being.
