"Google, in doing so, also penalizes websites that have different URLs pointing to the same page."
Legitimate Blogs Are Penalized Too
For example, you started a new blog with Blogger.com. You made 3 posts, one everyday. Your main page http://yourblog.blogspot.com lists 3 posts, which is identical to the archive, http://yourblog.blogspot.com/2007_03_01_archive.html, showing the same 3 posts.
To the search engine, this is duplicate content. One of the URLs will be "supplementaled" or worse, delisted from the search engine database.
