While the part of playing without a soccer ball may be a joke, the part of not keeping score is a fact for certain age levels. My kids, both 11, play competitive soccer, however no official scores are kept for league games, and this is a joke IMO.
I know for a fact that the kids keep track of wins/losses so the concept as set out by the Ontario Soccer Association is flawed. In close games, the coaches play their best players and are playing to win, so the whole "fair play" concept is not working anyway.
In competitive sports, there is a winner and a loser. The kids know this, but unfortunately the people making the decisions don't see it the same way
