Let's actually look at these reasons:

This is not at all how I use virtualenv. For me virtualenv is a sandbox so that I don't have to become root whenever I need to install a Python package for testing purposes

This is needing to install multiple versions and use the newly installed version for testing.

and to allow me to hop between sets of installed Python packages while developing on multiple Python projects.

This is the ability to install multiple versions and specify different versions for different projects you're working on.

I also use it as a sandbox for build bots so that multiple bots on the same machine can each build their own projects with just the known dependencies installed. This is the only use in the list that is virtualenv specific. The rest are cases of needing to install multiple versions on the system.
