He is obviously correct about the specific narrow statement made here and it’s so annoying everyone has to be memey mad about it like a bad reddit thread.
And even in economic terms... the way free markets work is that we let dollars decide which resources go where. That's the "optimal" distribution of scarce resources - they go wherever most values them. So his distribution is in fact economically sub-optimal. I value having some RAM more than he values having one more increment of RAM, so I get some and he doesn't.
He doesn't like it? Not my problem. Not economic theory's problem, either.
