Because (unless there are some generally accepted tools for doing so) 
you (as do I, and others, but not everyone) know how to spin up a chroot 
with all of the properly mounted virtual filesystems, etc.  Doing this 
is not as straightforward to the linux newbie as installing from media 
into a completely virtualized version of "the computer" they are used to 
dealing with normally.

Not that I'm advocating the (ab)use of VMs where chroots are sufficient. 
  I'm just saying they are not as straightforward as VMs.
