Capitalism has its downsides but one thing that it does better than all previous known systems is efficiently allocate resources that result in productivity. That is, it is the most efficient system we know.
Investment that does not result in utility for the investor leads to reduced investment. This is true regardless of if the “investment” is money or talent”.
Your suggestion that a system that allows people to ignore the price creators demand for their creations will be more efficient has been refuted over and over again throughout history.
