It's quite simple: there IS a "tangible, quantifiable advantage to doing so". The problem is that you imply "...to the person writing the code". That's where your confusion lies. I am getting huge value from the people who built stuff before me. When I build stuff I can (hopefully) make the world better in the future.

But lift your gaze an inch off the ground and you'll see we don't need to be ego centric sociopaths. We can build together. For the species. Everyone wins.
