The poster above is trying to say that luxury branding has to have at least a veneer of justification for its pricing. The $1000 painted tree stump supposes its own value as a piece of art. A $1000 watch might cost $200 to produce, but it's jewelry - the whole point is you're paying for the pure aesthetic value of it.
The monitor stand has a nice appearance, but everyone understands that it's a mass-produced, functional product that can't justify its cost artistically or by virtue of materials and construction. The stand is also usually included with the monitor!
There's a clear message change. We've moved from "this is the cost of luxury" to "this is the cost we've greedily slapped onto a random part you need"
The difference between the two isn't vast- you have to pay attention to the nuance here.
