No impediment exists to anyone posting the entirety of their own content.
On the off chance, you actually didn’t understand what I wrote... I was referring to the possibility that the response to an excerpted blog could be to post the entire content. This approach would remove the incentive to provide the blog with multiple pagehits, and not disrupt the FR conversation on the topic of the post.
I did not state there was an impediment, I’m not sure where you got that from.
