yep, the curb cut effect is a well-researched and documented phenomenon [0] across ADA development in all aspects of the world.

accessibility work isn't just about making things possible for folks with disabilities, it's about making things better for everyone.

Another way to think of this is that everybody occasionally needs to do something unusual. But some people, due to their life circumstances, always need to do something unusual. And making things better for the always-odd folk is also a positive to the occasionally-odd folk.

Which like, we're all eventually gonna be odd folk! That's what age does to us. But we should understand these accommodations as being a net positive, not a cost, to society.

Yep. In accessibility research, they call these "situational disabilities". When you need to open a door with your arms full of groceries, you aren't so different from someone who is never able to open a door. Accommodations that help people with permanent disabilities also help other people in the right situations, too.

My touchpad broke and I couldnt download the touchpad driver to fix it on the spot because there was no way to get to the download button with tab and enter, you had to click it.

That's a funny example, reminds me of how often fresh Windows 7 or older installs were missing the ethernet driver so you had to move stuff over on a flash drive to get started really setting stuff up.

In your situation, a couple possible solutions come to mind. 1) turn on "mouse keys" which lets you use the numpad to move the mouse and click, 2) a vim addon for the browser (e.g. vimperator or tridactyl) likely could've clicked the button via the hints mode. It's in the past now so maybe these wouldn't have worked or you didn't know, of course, just fun to think of what I would've done.
