Exactly. Or equally: money can only exchange hands by means of a leaky bucket. But I'd say that it's not a big problem that the bucket is leaky. Goodhart's Hell is when that extraction industry dominates or that bucket isn't so much leaky as it is missing the bottom which differentiates it from a tube. Some people call this peak capitalism and it's right to complain, but I think this happens in whatever system you use, just exhibits itself in whatever metric dominates (in our case capital/dollars. Also typically capital/dollars in communism too because both systems are explicitly about capital ¯\_(ツ)_/¯).
