People with disposable income like to find ways of making their hobby expensive. HiFi people want things other people can't hear, car people want them to be impractically shiny or fast. Camera people own perfectly good lenses but want one four times the price that's 10% better. It's a way of justifying an urge that only makes sense in the asylum they inhabit.
The assumption that such things are for listening to music, or a means of transport or of making pictures are met with same pitying incredulity reserved for the mentally impaired. It goes up to 11, manufacturer's make them and other people own them so, duh...
