FIFA / UEFA has a monopoly on international soccer. They sustain the monopoly leveraging micronations that effectively gives them a majority in all of the monopoly's decisions. When Germany has the same amount of voting power as Andorra, you have a problem.
Of course, this majority is not secured by good policy, instead it is secured by corruption, payouts to micronations.
I think another league -with different ownership and stakeholders- could make things quite interesting because it would take money out of the system.
However, i'd like for fans or players to own the alternative system, not clubs owned by PE firms and their buddies.
