I think you're looking at this from a solo dev's perspective, where all you do is get up, bang on some keys for 8 hours without anyone else bothering you, and then you're done. Of course that works in a corner of your bedroom where you live alone, but that's not everyone's job and living situation.
No one is arguing that a dedicated office isn't desirable. It's a question if someone else should pay for it if you want one.
I think it's not a matter of want, given the kinds of situations I laid out. In my situation, I have ADHD and I'm autistic. If you want me to work I need to be alone to work. It's not a want or a desire. I cannot work in a room full of people and noises, so putting me in one is just the same as expecting me to code without a keyboard.
My employer gives me a computer, why is it such a stretch that they also give me a room? They want the work done at the highest quality, don't they? It's making them a lot of money, isn't it? So what's the problem?
But see, this isn't my problem. The money the company gives you might be a lower pay raise for me and others who don't care

That's 99.9% of the cases
