That is exactly my feeling. And with all the talk of minimizing the clicks why drive a visitor to a page with no content just to find their way around the site. The home page should have obvious navigation to all the major sections of a site. Then the first page of each section should have navigation to all it's major subsection. The visitor should be able to return to the home or main page from anywhere in the site and this will serve as the site map to the major categories.
It's rude and disrespectful to your site visitors, and not to mention completely ugly from a design perspective.
As a website visitor if I could not find my way around through normal navigation I would leave.
One of the rerason I started this discussion is that we do not use a site map on our corporate page. I have thought about it time and time again and just can't see what function it would serve. I invite anyone to have a look at our site and tell me if you really feel a site map would enhance the site in anyway.
