Precisely. If they don't honor their contracts, you can do fuck all about it. If a government is behind your contract, that is usually not a good thing in terms of being able to actually enforce the terms of that contract. I get your point, today it looks like it is sure money. But who knows what they decide in two years time.
And they have potential to recoup some of this insane money long term it if they make their huge domestic market base interested in football big time. Also they just dont want to go out on foreigners alone, or they wouldnt have made the restriction of only 3 foreigners per team. They spending billions on infrastructure and youth development (quite naive to want to speed things up this quickly, but it will eventually bear some fruit with amount of coaching talent know how they import), they massively increased their attendance and domestic broadcast ratings etc. All indications for this NOT being something they will abandon on a whim. They even bought European clubs or invest heavily in (in City's case), with the express intention to learn how to build up successful clubs from the ground up.
