The whole point of having language and intelligence is that it should be used, not just discarded with some discredited hand wave that "if we just do nothing, everything will work out for the best!"

Centrally planned economies have been tried. The Soviet Union discouraged a lot of research into areas like psychology that they saw as pointless; artists had to conform to traditional styles. It didn't turn out very well. Letting the market allocate resources has a lot of inefficiencies, but it works better than any alternative that has been tried.
