The premise itself is fiction. The P in GDP doesn't stand for exchange or transaction. It stands for "Product." It measures the net amount of new wealth, not how many times existing wealth is transferred among parties. If I sing you a song and you pay me $1 million dollars and this process continues back and forth, the net amount of value when we stop is still $1 million and the net change to GDP is zero.

People indulge a lot of strange and wrong ideas about economics and, not surprisingly, those bad ideas are typically well aligned with their preferred world views.
