I think the HN community will much prefer having an unmoderated HN over a moderated HN with a bit higher quality as the main reason why people come here, is that the content here is solely selected by the community.

If however, people find out that HN is much more a controlled environment, they will surely turn away from HN. So instead of trying to control the whole thing just in return for a bit of increased quality, rather sacrifice a bit of quality for an open HN. Of course there can be some moderation, however, it becomes a bit tricky when titles and content is changed, and upvotes are controled.
