To answer the question more directly, I tend to pack lighter because of common sense. Hike smarter.
Ultra light hiking is great, but if you hike so light you are bumming food, water, and/or shelter off of other hikers, or if you raid Cache's left by other hikers for those truly in need or to give others a "boost" as is the tradition-" Take a little leave a little" was the code in the past, then you are a Tick. Parasitic hiking is not true Ultra light hiking, and many people who claim to do it over extended distances are pretty much ticks.
Modern gear is usually lighter than the older stuff. There is no reason to be uncomfortable. True ultra light hikers have a much higher than average skill set and are in much better shape than most mortals, but they also usually are competitive, and the trade off seems they don't stop to actually enjoy what is around them.
