I don't know if "banning" is quite right, sometimes the article only exists behind such a structure, but may be worthwhile for the community to discuss. Mods already replace higher quality links after they show up in the discussion. The same could happen by submitting a prominent paywalled source to get the discussion rolling, and then as a better source is made or discovered switch over to it. And the comments on HN seem to be more coupled to an event than any given particular article, meta-metadiscussion aside.
