The term 'camping' is a giveaway; we're not talking about the same thing. Camping is pretending to be homeless for a night or two, usually within sight of the car or truck that brought you there. Backpacking is where you travel many miles over rough terrain to spend the night in some scenic spot carrying everything you'll need on your back.
Most (~90% or more) of the hikers and backpackers I know don't carry any means of self protection larger than a folding pocket knife. Of the few that do carry protection, most carry bear spray (~9%), and only a very few carry a handgun of any type.
It's not a war zone. Incidents where a firearm of any type would be useful are
extremely rare. The time you spend at the trailhead is probably the most dangerous. We have thousands of hikers and backpackers here crawling over the terrain every month of the year, and I can remember only one incident where a firearm might have been helpful; a mountain goat attack.
Statistically speaking a firearm is unnecessary. Some of us carry one for several possible threats, all of which we know are very unlikely. For the places we frequent, your suggestion of "shedding a few ponds of equipment" is unrealistic. We carry only necessary survival gear, necessary food, and a few luxuries (camera, sleeping pad, fishing gear, etc.). Since hypothermia and falls kill and injure far more people than the wildlife, we prioritize our gear for those threats.
I'd much rather hike farther over rougher terrain to get away from the yahoos, and to do that my gear has to be lightweight.
