This is analysis of results not possibilities. Having possibility doesn't means you have to use it. Having possibility to walk doesn't means you will walk same route and distance as an other person who has this possibility too.
Something is "possible" if we have an expectation that it might come to pass. How should we analyze possibilities except by looking at what actually happens? The premise of my counterpoint is that there is a probability distribution attached to what's possible, and that the distribution is not the same for everyone.
