Karaya, Ink,
I don't deny there is skill involved. He's certainly smart and tech savvy in the ways of building and fabrication. However it is not art deco. It's excess for the sake of excess. Not to be confused with, say, paying to upgrade a PC because you're going to run a lot of stuff on it, or some heavy high-end stuff. It's not even excess with the intent of breaking overclocking limits and earning fame/acclaim that way. It's simply extravagence. Shrewdness is more than that.
No my Ferrari comment wasn't a direct comparison, but it was a tale of wasted money and that's how I meant it to relate.
I think "intent" plays a part in whether it's praise worthy or not. If ask: Why do this, and the answer is: "Because it is the best way to do X or Y" that is one thing. If the answer is "Just because," it lacks aim, direction, or focus. In this latter case is where I'd lump this desk.
There's a socio-cultural aspect to it to, I suppose.
