Very true. But this is often due to just random luck. Any mid level PC with a reasonable con score can fall 50 feet once per day and be totally fine. There may be one or two people on earth who can do this, if at all, without trickery/artifice.The thing with falling damage is, normal humans have survived falls from some pretty insane heights (Vesna Vulovic's 33,330 foot drop, though obviously, she was far from "just fine" afterwards; Nicholas Alkemade got off the lightest, with a broken wrist and leg after 18,000 feet), so it's one of those things like being struck by lightning. Some regular humans die. Others don't. So luck, divine providence, training, soft landings, what have you, there's a large chunk of what hit points represent that's obviously not structural integrity.
If the game had a mechanism where each fall had a very small chance of resulting in no damage but probably killed people most of the time, your argument would be more valid but...
