I’ve been wondering the same thing myself lately, the only advantage I can think of this accumulated information on the site (in the form of Q&As). I’d imagine a majority of SE traffic is people reading old questions, though if anyone knows this assumption to be wrong please correct me. I also wonder if scraping the Q&As and posting elsewhere would be some sort of legal violation? It would be fairly trivial to host the current body of knowledge up to this point on a static site and then start fresh.

The (unilateral) relicensing was another recent issue, but generally not. All user contributions are licensed CC-BY-SA 3.0 so I don't see legal reasons stopping you. Google won't send you any traffic, though, because it will be duplicate content and the original has a gajillion links pointing to it.
I link to websites when I copy someone else's code, for attribution. How do these "build pipes" expecting me to do it instead if the code is from stack exchange ?
