Software environments, languages, and other such abstractions aren't there to be perfect. They are there to help human beings manage absurd numbers of machine instructions. Maybe when we fully understand the human mind, we'll figure out the perfect way to map machine instructions to concepts that humans can grok. Until then, we'll have to make somewhat subjective design decisions in the face of uncertain constraints and priorities, which is certainly not going to lead to a "best" solution.
