C'mon Rob, you know that's a false equivalence, for multiple reasons.
I've never seen anyone hit their head seriously on a backpack hunt, or have a limb fall on them. Even if it did happen, that's a straight-up accident, and not something one would expect.
However, backpack hunters do test their bodies to do what they need to on extreme hunts - they train to do what is reasonable to be expected in that situation - such as gaining and losing elevation, long-distance endurance, agility over scree and boulders, ability to handle cold, and so on. Put most people (including people from other hunting and shooting disciplines) through that training, and they'd possibly call it abuse. But it's not to the people who are choosing to do it - it's just getting fit for the task.
Similarly, it's not uncommon for rifles to fall in this context, So this testing is just to see if the scopes "fit" for purpose too - no-one's saying to do something unexpected or unreasonable (like pounding nails like in an NF ad); they're just quietly testing their own gear to see how it would fare if it took a spill - again, not uncommon in mountain hunts.
If others don't need to, or want to, test their scopes, no problem.
