Billions locked up in deference to a handful of CEOs means less liquidity in the open market. Which is intentional, I understand; if dollar value collapses these guys might have to work to survive, and of course humans could no longer do the necessary trade of real things to stay alive and prosper if an arbitrary financier cannot claim an arbitrary % of economic activity thousands of miles away.
Human agency is coupled to wishful thinking still. Which is understandable; we only just crossed the threshold of <50% of adults believing in higher powers. Was still 80% around 2000.
