I'll agree with your general thesis, but add my own observations about physical power. It's also relaxing, knowing that you could control the situation by force makes it much easier to stay cool and controlled when things are difficult, and in it's own way is very calming. I know that I'm not unique in that I feel better about nearly any situation if I have more options, it's when I feel cornered and out of options that I tend to react badly. Between my martial arts training and the weapons I carry, I know that I have power over any given individual that I might be dealing with, whether they know it or not, and having that option makes it much easier to be calm and not rise to provocations knowing that I have the ultimate advantage. It's kind of a Zen thing, having the power makes you not feel the need to use it, which makes you feel even more in control, etc etc. Physical power is in some ways the most accessible and the most powerful of all power structures, monetary power or political/social power may give some protection against it, but it is still possible for someone with a little physical power to overcome someone with a lot of the other kinds. Therefore, I believe in building one's entire power structure on a foundation of being physically powerful, because it's the only form of power that is not dependent upon the cooperation of others to be effective.
