Clothed, or not, there is an element of solo hiking in "wilderness" that has to muster some courage. It is more dangerous alone, no back-up. A stumble, fall, wrong trail, and/or emergency can be fatal. During encounters with animals, solitary instead of two or more, you don't out number them. While I may miss something, my partner might not. So, I see doing this nude as one of the minor concerns, or fears.
On the other hand, nude, there can be a sense of being closer to other forms of life, or nature, or a God. With full senses, more aware, closer to myself and faith in that. I find this more so when I'm naked. All of these can be protection, or confidence on a remote trail, or even life's journey. Thinking somewhat like the 23rd Psalm, I am closer to an abandonment to a higher power, and even more so when naked. It is some amount of surrender and faith. It is to be and feel more primal and our innate being in nature, is a protection that we are born with. It is something that gets lost here and there and needs to be used in order to keep it, or rekindled. (sorry for the odd paragraph structure, I should probably elaborate more. I hope that all goes together for your understanding, and you identify with it)
Naked is more real, authentic and to be what is the richness of our humanity. On a trail, solo, is certainly that.
