I used to think the same way as you. Then I got RSI and the only thing I can type on now without excruciating pain is my $250+ ergonomic keyboard. The other day I typed a short password on my Corsair gaming keyboard (standard layout, full size) and I literally sprained my left wrist immediately.
Honestly, after how much money I’ve spent trying to deal with my RSI (doctors, exams, physical therapy, home workout items and programs) the 250 is nothing for something that isn’t exacerbating my injury and in fact reducing inflammation enough that things are finally healing.
FWIW, I think the commentary around pricing is totally valid. Ergo keyboards are absurdly expensive; not everyone can drop the necessary 2 to 400 USD to acquire one of these. I don't know the economics but I'm sure part of it is driven by demand; there's a lot less people concerned with ergonomics than there should be, so no one's really incentivized to figure out how to mass produce these.
I would love it when an entry level ergo keyboard could be had for under 50.
