People's urge to create wonderful things did exist in the millenia before 1750, they did exist in the eastern bloc, and every day today multiple great things people do in their free time, making no economic sense at all, pop up on HN.
Even in capitalist societies many if not most of the groundbreaking inventions and discoveries were and are state-funded.
