i disagree massively - different materials have different properties and they do different things - if you stand in driving rain for hours on end in a waxed cotton jack, even if it was professionally waxed the day before, it will eventually wet through. you could stand there for a month in a gore-tex jacket and the water won't come through - and personally i don't find the waxed cotton jackets much more comfortable to wear than a decent membrane jacket: a bit, yes, they are more a bit comfortable to wear in a warm pub than a gore-tex, and on a warm day - but i don't wear one on a warm day, i'd rather get wet from the rain than get wet from sweat and be all clammy.
the advantage they have, imv, is how easy they are to repair in the field, the disadvantage they have is that its a right faff to reproof them.
conversely, i don't know anyone who doesn't prefer a merino baselayer to a synthetic one - they are just much more comfortable to wear - for mid-layers however synthetic fleece trumps wool every day of the week: it weighs about 25% of what wool weighs, it dries quickly, its still fairly effective when its wet, and a £25 fleece jumper will be as warm as a £70 wool jumper. if i go to the pub i'll wear wool, coz i is well classy, but if i was to do a 5 day walk across Mid-Wales in November i wouldn't touch wool with a 90ft bargepole (insert sheep-shagging joke here) - if i got it wet on day one it would still be wet on day 5, even if i stayed in bothies every night with an open fire. no thanks...
I can see your point, but I have never seen a sheep wearing synthetic fleece, and they survive all weathers (grew up in wales, live in wales, and spent years working on a sheep farm) I can understand from a comfortability point of view, but wool will still insulate even when wet, not comfortable but will keep you alive. I prefer natural over synthetics from a greener way also. My wax cotton and wool will rot away, your gortex, nylon and polyester will be still be stuck on this earth for up to 1000 years! In a non usable state. Just my way of life, doesn't mean either of us is wrong, just two different opinions. Still keep my velcro gloves though
