You would be correct if I was building large content heavy site, but
the scenario I had in mind would probably be for a small, other was
static site.

Again, I see your point if I was building a web app with rails, but I
am simply trying to add some functionality to a small site.
I could use php includes, but sometimes that would even be too much.
Imagine this scenario.
Let's say i want to link to a particular answer on a faq page. the
answer is in it's own container with a named anchor. even if that faq
page was using a php include for the content, it would most likely be
all the questions and answers, and not an include for each question
answer.
