I suppose its about the ROI.
Everyone values different things, differently. Therefore, the return on the investment to get what THEY value will differ.
For example, just step back a moment, and say "why would some one spend $400 on a fancy flashlight that's made beautifully?" For a Flashaholic, its OBVIOUS why...but to, say a stamp collector,...it has NO value. IE: YOU CAN understand why someone would want what YOU want, but you CAN'T understand why someone would want something that doesn't appeal to YOU.
IE: Why just a fancy light? - Why not buy a rare stamp instead? What about investing in gold? A good mutual fund? Baseball cards? Is that the BEST use of your $400, on a FLASHLIGHT?!?!!?!
Why not have a trit encrusted wrench? A supremely well crafted and beautiful stapler?
What if you just wanted the stapler to be covered in trits, because you like the look? Does it HAVE to be a titanium stapler made by had in a mountain forge by specially trained virgin fairies, or is a Swingline, etc, ok to decorate?
Does it MATTER to you WHAT stapler you decorate?
What stapler do YOU USE? Is it a gorgeous hand crafted custom stapler that will last forever? Why NOT?
WHY would you waste money on a cheap stapler when you could have a custom titanium masterpiece instead?
See where this line of reasoning goes?
