The consistent attitude with regard to the golf language situation is that for every challenge, each language is a category, and subsequently there is a 'winner' for each language. This is also a very very popular opinion with regard to the new user experience.
There is a problem with this idea. With the exception of a very small percentage of languages, Most challenges have only one answer for each language. You might see where I'm going with this. If there is one winner for each language, and also one answer for each language, then by extension almost everyone is a winner. Anyone with a half-decent answer is never challenged.
By this logic, why is competitiveness important to the PPCG stack?
Does the reason expand beyond "The rules say so"? If not, then why are the rules discouraging competition?
After some confusion of definitions, a formal definition of competitiveness:
Possession of a strong desire to be more successful than others.
