The nichier the market, the more price has to go up to compensate. I also doubt there's much competition in the field, other than DIY or not using a convertible desk at all.
There are actually more options for height adjustable desks than you might imagine. I wrote up a post a while back that listed 7, but commenters have since added quite a few more.
It's not quite that simple because the high prices force the market to remain niche. It may be that the market could become surprisingly large if an affordable commodity version of this were available.
If you saw a day in my life, "hyper-sloth" would more likely be your term for me. "hyper-optimizer" isn't even on the list of possible descriptions. And I use an adjustable standing desk.
And no, ergonomic suicide is not an alternative to a proper desk with external monitor, keyboard, and mouse.
