I know this thread is probably dead, but just feel like responding: the factor you’re leaving out is that having multiple people competing to develop the best knife leads to better knifes.
This is old school Econ 101, but I think it’s relevant. Know we have multiple options for knifes. How do we decide the best one? We let people decide for themselves, and price is the signaling mechanism as to where resources should be focused.
So we have a “market mechanism” for discovering quality, thereby making “market” an integral part of the system.
It could be done otherways, and markets have known weaknesses, especially for certain categories of goods.
But for many categories of goods it’s a very powerful system to spur and support innovation and entrepreneurial endeavors. So to call an essential part of a market bases system valueless does not make sense.
