I'm glad you enjoyed reading my post; I've certainly enjoyed reading your followup.
I completely agree with your first point, going to show that I wasn't quite clear in my original post. I do not adhere to any religious dogma. Choice is good, variety is good, and the more of both, the better. Having a personal choice made for you and limiting your ability to make individual choices, whether for religious, political, or other reasons, is unacceptable. I'm merely commenting that, for me, putting in some time and thought at the beginning of a process--carefully weighing as many choices as I see fit in an open-minded, thoughtful manner--allows me to take the often stressful task of making persnickety choices out of the equation from that point on. So if I'm looking for a great sleep system, I look at everything, take advice, try lots of things, make some critical decisions, and then--done. It does what I want, how I want it, when I want it to, allowing me to focus on my real goals: mental, emotional, philosophical, and spiritual contemplation and appreciation in the backcountry.
I think we're actually in agreement on your second point, as well. When I say redundancy, I mean either owning or carrying more than one piece of gear to fulfill a specific task. So, with your example, if I decide that carrying a watch with an altimeter, compass, and thermometer is the best choice for me in the largest variety of situations, I don't want to also be carrying a separate altimeter, compass, and thermometer. Ideally, I don't want to even own those pieces of overlapping gear (although in this case you have to consider things like batteries and extreme weather affecting the watch, so maybe you need tried-and-true backups in your gear closet for more crucial excursions). If I have one great solo cookpot, that's all I want both in my pack and in my gear closet: one. And since it'll make a great cup, storage unit, and maybe even something else, I don't want separate items to do those jobs. Multiple use all the way, baby.
The real balance for me is sacrificing a little bit of performance for simplification. To keep with the cookpot example, if there's a cookpot that's maybe a bit better for some really specific purpose than that one that I own, I'd rather just keep the one and exchange the small performance gain in that one situation to simplicity gained and money saved overall.
So... we cool, friend?
Edit: Roman, when a conundrum comes into your immediate vicinity, it is absolutely imperative that you lash it into a better state of being.
