Why is deciding what nation has the best ball kickers relevant to anything at all let alone be an exercise of power to hold said competition?
The simple fact, that Qatar bothered to buy the whole thing shows, that it is important.
It's interesting, growing up, I had friends with a hobby for supporting particular footbal teams in my city. And of course rival team supporters couldn't really be friends, to the point of full out violence between rivals being an every day thing. I always asked them why is that, because except for the color of their scarf they fit the exact same personality pattern - they all would explain it from a mythological history of tribalism point of view that did not make much sense to me at the time.
Fifa also has rules preventing this. You cannot switch national teams, once you played for one.
It is actually the other way round: After the poor performances in the early 2000s, German clubs have agreed on a few rules regarding how many foreign players are allowed to play on each team and what each club has to do to train new young players. The richer clubs basically restricted what their own money could buy. These regulations are widely regarded as the reason for the dominant years during the 2010s.
