How can you possibly allocate resources efficiently if you don't consider whether those you are allocating to are competent? What do you propose? Derisk with massive government bureaucracy?
Ultimately, scarce resources, which take their own industries to produce, need to be allocated so the many goods and services we need and want can be designed, built, and/or executed/delivered. If you do not rely on merit to decide who does what, everything will absolutely collapse.
By “meritocracy” I mean the idea that it is morally just for people to be rewarded in money or social status proportional to their economic usefulness — an idea most people implicitly hold to some degree and which some libertarians trumpet as a core tenet. I think the implied inverse to this belief — in the extreme, that lack of economic usefulness deserves poverty — is morally repugnant and dangerous.
