Usability is also a big reason to not wrap giant blocks with an anchor tag. Anchor tags should be text (or an image) that clearly indicates where they are leading the user to. If you're linking all parts of a block to something, there are serious usability implications. Why not just link the title of the article? Or throw a link at the bottom that says "Read more"? You can't say the anchor tag is broken because you're trying to use it for things it's not intended for. That's like me saying my computer is broken because it can't make me a grilled cheese sandwich.
