Personally, I find a lot of truth in what you say but I vehemently disagree with the premise that we should accept death as the price of life.
Of course, we need to be realistic and acknowledge that everyone living will all almost certainly die one day but that doesn't mean that we shouldn't strive for a future without death.
I think that CGP Grey's video, Fable of the Dragon-Tyrant, does a wonderful job arguing this viewpoint.
