Well, Apple ships certain libraries, and they want them to be on your path.

The nice thing about virtualenv is that, along with pip wheel caching, re-creating them is really fast, so you don't have to just do one setup; you just make a requirements.txt for each separate environment you want, and regularly re-create it, so you know that if you give directions to anyone else, your setup will work for them as well.

One bad habit we get into is getting a full-on environment set up on our own workstation, and then not knowing exactly what we installed, and therefore what we need in order for someone else to build and work on our software.  Virtualenv helps reduce that problem a bit.
