Rich, it sounds like you have much to learn regarding UL backpacking, and that's perfectly acceptable, we all do. UL backpacking is such a subjective and personal experience, what works for one individual in Bozeman, MT doesn't always work or isn't exactly necessary for another in Moab, UT, get my drift? Take what people say here with some grain of salt, and know when to take the years of wisdom and experience that many have to offer here with discernment. Apply or don't apply what you read here in your own forays into the backcountry, frontcountry, backyard, whatever. At the end of the day, it's your time outdoors, spend it how you like to and don't get caught up in brands and cottage this, or REI that, because unfortunately, your "People are ruining backpacking" rant is doing exactly that. You end your tirade boasting about what gear you're going to be sleeping in for the sake of humor, which serves no purpose here or is in any way edifying or positively contributing to the forum or your point of view.
Also, as far as personal attacks and generalizations, it's really easy to sit back in the cockpit of an armchair with a laptop in hand and throw out barbs at individuals across the country whom you have no contact or experience with, so it's best to err on the side of caution and "benefit of the doubt" issuing, a big dose of humility goes a long way online, especially considering how much content is taken and pulled out of context.
Lastly, just for clarity's sake, I've been conducting a personal test with my BPL Beartooth Merino hoody, I've worn it for 6 months for everything from weekly trail runs, bushwhacks, around town, multi-day backpacking trips and have yet to wash it or noticed any stitching or durability issues, even with my pack shouldered on 25 mile days. Not bragging, just sharing with you what I've seen. Again, that's my own experience with that item, a further testament to what works for some doesn't work for others, let's not throw out too many erroneous misconstrued facts or rely on other peoples post to serve your purpose, as you did in your OP. Hike your own hike, live your own life.
