It's your prerogative to do what you want with your machine.
Caps lock being on the home row is a bad design in my opinion. Remapping it to something useful is making your hardware work for you, not against you. You obviously can't make your coworkers change their behavior but you're completely in control of your own, where most of your work is likely being done.
My hardware does already work for me. Remapping caps lock is a micro-optimisation where as committing keystrokes to muscle memory is not. So the jarring effect I'd experience when switching back to a system that doesn't have caps lock remapped would easily outstrip any benefit I'd receive from it.
I switch between different keyboard layouts fairly frequently (I use a kinesis advantage 2 which is quite different from traditional keyboards) so maybe it is just being used to being somewhat uncomfortable when having to type on other keyboards that is making it harder to appreciate the difficulty it actually presents to others.
It seems like you are using different keyboards constantly so fixing it on one laptop maybe doesn't offer you much benefit. I doubt that everyone that reads this is constantly changing keyboards, though. For those it would certainly be beneficial unless they are for whatever reason using caps lock frequently.
