Now I am imagining a world where profit doesn’t stop.
Like all the money gets centralised more and more until everything is owned by a single tiny group or even one person. They literally have all the money in the world.
And everyone else just … stops using this money, since there is no point. Then they start using a different form of currency like pearls because that is the only way now to trade between non-owning people. Making all this money completely useless.
