You seemed to have missed the point(s) of writing software. Or rather, are focusing on the reasons for using software.

I think you are suffering from survivorship bias

Code has a finite lifetime, often surprisingly short. I think its often cheaper to fix faults in code that survives than invest lots of code, much of which does not survive.

Of course there is a cutoff point below so little has been invested that rewriting is cost effective.

That red door stopper is primarily customer oriented.
