If you were able to toggle HN from tree view to chronological view, it would be borderline incomprehensible. With tree views like HN, nobody bothers to quote what they are reacting to because the placement of the post will usually make that obvious (I note that you did quote, but none of the responses to your post quoted you.) I see the same on reddit. There are UI change you could make that might solve this, but classic forums and HN/reddit each encourage different behavior.
To me HN and reddit are single use. I go in and read comments once, but I never go back, because when they go back, there is no way for me to know what I have and haven't read (maybe there is in reddit--I don't really use it and have no account.) There are probably things HN could do to mitigate that issue and still retain threading.
You can have a chronologically sorted tree view - sort each subtree chronologically and then the root comments, keeping the hierarchy. HN doesn't do it because it would undermine the goal of karma sorting, and potentially lower the quality of conversation*. You could arguably do it with a flat view (I've seen some alternate HN views posted as Show HNs that do so) but you would have to add chan-style greentext links to everything which IMO makes things uglier.
* It probably wouldn't really but HN is incredibly paranoid about that sort of thing. Pun intended.
