At least Norbauer immediately states that it's "probably the world's most insanely irrationally hyperengineered keyboard" and later on continues that "nobody needs a 3000 dollar keyboard."

It's clear from that it's a sincere hyper-obsession, shared by others within a small community. I can respect that more than just making something expensive for the sake of appealing to ultra-rich who wish to flaunt their wealth.
