Markets as a general thing are essential, I agree. The particular market configuration that we have in this context is bad and tends toward oligopoly. I'm sorry for not articulating this more clearly. I'm sure you don't think that all markets are equally efficient or sustainable, but that individual markets can be more or less good depending on how they are structured and how competitive they are.

Attempts to use central planning instead have been universally disastrous

Nobody mentioned central planning except you.
