I think with anything, you get used to it. I've adapted to my keyboard. It seems to me a lot of people who complain about this keyboard tried it, but don't actually have it. (Obviously my opinion, not based on fact or a generalizing assumption).
I have a butterfly MBP at work but it's stuck in my drawer as a 'loaner' because of the keyboard. I find it horrible to type on. I use an iMac with an older-gen USB keyboard now.
I don't want to spend days getting used to it as you have. A computer is a tool for people, we shouldn't have to adjust to it. It should be adjusted to us. It's called ergonomics, something that Apple has forgotten about since Jony Ive's focus on thin and cute design above everything. It's the same with the "Magic" mouse, I can't use it (I have RSI and it literally hurts to use it because it's so flat and offers no palm arch support).
I tried using it for a few days in the beginning but as I also work with Lenovo thinkpads which have the best keyboards available on laptops I was constantly reminded of the difference and the MBP (as well as the "Magic" keyboard of my iMac) ended up in that drawer.
