Justification isn't really a thing in that market (see also: luxury watches).

My friends who are into hi-fi/audiophile stuff who value accuracy typically do go for studio monitors or similar (e.g. Harbeth) vs. stuff like Wilson Audio. Some of them still buy fairly woo-woo stuff like spendy cables even though they might know better, but at least they don't go in for the pure scam stuff like Shakti Stones or directional Ethernet cables...
