And they are right - the risk is there, and a person backpacking alone has a responsiblity to be very careful to avoid trouble.
But I think that something is lost in all this good advice. The hard fact is that good sense and good health may delay the inevitable, but will not change the fact that our lives our short and not one of us will ultimately survive.
The problem as I see it is not how best to avoid death, but how to live well. For some that means backpacking into wilderness alone.
Time by one's self is underated as a quality for a healthy individual. In solitude you learn plenty about yourself and can discover a strength you were unaware of. Solitude can cause a turn in your philosophy towards a belief in the divinity in the universe. Going alone in wilderness seems to facilitate these changes, since you are away from the busy activity and diverting gadgets that fill a normal life.
Standing before the beauty of a mountain wilderness in solitude can make one feel as if they have stepped through the door of heaven and now have the opportunity to walk within it.
Solitude and lonliness are not the same thing - The beauty and peace and power of a wilderness is such that what you witness in nature in one day is life-filling, and the emptiness that characterizes lonliness drifts away.
The response of an individual to wild nature is much like that of music, or art - everyone is affected by it differently.
