For a few reasons: there are lots of ways to abuse those features, which unfortunately some people would take advantage of; we want to preserve the history of the threads rather than have them be gutted or anachronistically edited; and because wholesale deletion would be unfair to the other commenters who participated in a thread (pg wrote about that way back: https://news.ycombinator.com/item?id=6813226).
That doesn't mean we don't care about protecting users with privacy and other concerns—we certainly do, and like I said we take care of these every day. We just try to do it with more precise tools than wholesale deletion.
It's fundamentally a tradeoff: we're trying to balance the community interests of a public forum with the need to protect individuals. There's no perfect answer, but we're committed to both sides of it. Of the people who ask us for these things, well over 90% end up satisfied. Probably over 99%, but I don't want to make claims I'm not sure of!
