Alex88 was killed by being carried into trees this season in Utah. Trauma is a serious problem when you get carried by an avalanche. The guy in Telluride who was killed in the sidecountry there, had it all. Avalung, Airbag, beacon, etc. He triggered a slide and got taken through the "bread slicer". Trees, rocks, and such. Airbags work great on slopes where you don't have very many obstacles to run into. Not so great in terrain with lot's of trees and/or cliffs and rocks.
We carry the rescue gear for when everything else fails us. Our decision making is the number 1 asset in staying safe out there. When the shit hits the fan, that gear is your last ditch chance if you survive the burial process. Tons of examples out there where a person was buried or carried by an avalanche, recovered in mere minutes and still passed.
You don't want to be on the receiving end of an avalanche. Plain and simple.
