Actually I think you're wrong. Dead wrong.

I think that Hive account@bluechoochoo is totally right. She's quite aware of what a blockchain is, and how posts on one are indelible. She probably even knows that steemit saves just diffs in the casess of edits, which is actually another strange anti-pattern as saving the diff only causes all kinds of wierdness for coders trying to extend steem/steemit.

Anyway, here's what I think her point is, and certainly what my point is: just because a post was a certain way in the past, and you considered it perfectly fine that your post was indelible, doesn't mean that it should be that way today. This actually matters a freaking ton. Now, remember-- it's a blockchain-- there's no way to delete stuff even if the UI here says it is deleted. It's not. It's simply not shown, is all.

Hive account@bluechoochoo is worried about her posts older than a month, because she makes frequent, sequential posts and might want to use some of her posts as a reference point online. God knows I want this, too. If such features were implemented, steem would look much brighter as a tool for professional bloggers, even if it was just another publishing avenue and a long-term datastore that their database or static site generator tapped into.

Let us not forget: Every post stored inside that there blockchain contributes to the value of the currencies.
