The $100bn number was an empirical observation. There is a limit on the dollar price of wealth created - the supply of dollars. More precisely, the total returns to VC investment from a given cohort is equal to nominal GDP times the portion of GDP that is the profit from companies in that cohort. Both of those numbers have soft and hard limits to them. Total wealth creation is indeed unlimited. But that shows up as increased purchasing power of dollars, not necessarily a higher return in dollars ( and it's the latter that matters from an investment perspective).
