Why use dynamic libraries if you don't need to save storage space or RAM?

We have moved beyond the era of scarcity and even on desktop platforms, lots of people are including static libraries so that they are not dependent on the upstream developers' idea of what is needed. So much of this code is open source that it makes sense to build your own static library, and maybe leave out cruft that you don't need.

Sure it would be nice to have a choice, but static libraries are not evil.
