haha, he just wants to build material for his site

and btw, I like your site
As for your question:
Experience is what counts. I guess being a "survivalist" is part of that? I'm just saying that you could have a situation where an inexperienced outdoors person takes tons of equipment, but the wrong equipment v. the experienced outdoors person who takes tons of equipment, but the right and good equipment. They could be carrying the same weight, but the experienced person will know what to bring.
Nowadays there are many light weight (not ultra light weight) gear options that allow a hiker to shave off 10lbs from what he used to carry - still might not be a 10lb bag, but going from a 45lb to a 35lb is still a big improvement. Is it safer? Safer from what? If we're talking injury prevention then anyone would have to say yes since the less extra weight you have the more mobile you'll be - although if you are hiking for months like thru hikers, your body will adjust to the weight of your pack after a month or so, so you'll probably be as safe.
Not getting blisters: I think that's really all in the fit of your shoe. There are 2 shoe sizes, weighed and unweighed. Weighed is the foot with weight on it, unweighed is no weight on it - I guess you could say that with a heavier load your shoe size could increase about 1/2". If that is the case then you need to get shoes/boots that fit that size and possibly some insoles to help minimize the foot elongation when it is weighed down.
I believe the fit, taking in all the expectations of the hike, has more to do with blisters then the weight of your pack.
So...
I think that in the end it's a mix between experience and comfort level.
I believe that as backpackers gain more experience and miles on the feet they tend to want to shave off unecessary weight (for comfort, for practical reasons, because they know they can do without it,or to become closer to nature) and go out there simpler...
...but they'll still be bound by their level of expected creature comforts.
Anyway, I could go on forever and I love talking about lightweight backpacking and different lightweight gear tips... but it's bed time.
