Assuming that the content you're publishing is primarily writing, then yes, that makes sense. But most companies on the web are not primarily blogs or news. Hell, even the way news is going, a lot of these Snowcrash-type (or what was that famous NYT article called?) articles are too complicated for a template-driven workflow.
The company I work for is a marketing company, it primarily uses the Internet for e-commerce. Our marketing team gives their ideas to our front-end guy, including mock-ups and copy, and he goes ahead and makes all the HTML/CSS.
I think most companies on the web wouldn't be able to tell the difference between a static site and a CMS, because non-technical people won't even touch an admin back-end anymore. There's just too much to screw up to leave in the hands of a non-professional.
